Fl is yet another character-mode directory and ZIP archive browser. It is just a REXX script, but it is nonetheless very easy to use. You just have to annotate the files you want to apply a command to with the desired command.
Suppose you want to print the 8514.RC file. Just move the cursor over the corresponding line, and enter "PRINT" (without quotes!). The command will appear in the prefix command (the area filled with "="s). You will have to press the Enter key to execute it (in fact, the Enter key executes all pending commands -- that is, you can prepare more than one command, and execute them in one step.)
If, in the previous example, you have wanted to print out the 8514.RC file while renaming ATTRIB.EXE to, say, SETATTR.EXE, you would have had to enter the "PRINT" command over the 8514.RC line and the "REN / SETATTR.EXE" one over the ATTRIB.EXE line. And then, pressing the Enter key in the main screen area would have executed theses two commands sequentially (that is, from top to bottom).
You can also use (and redefine) function keys to execute frequently used commands (such as browsing a file, or copying it to another disk...).
All colors and keys are redefinable. If you like the XEDIT look, you can use the provided PROFILE.FL:
You can open more than one directory at a time, sort them, or use a restricted view (e.g., *.EXE and *.CMD files only).
When you browse a ZIP archive, you cannot act on the content of the archive (e.g., you cannot remove or extract files). You can browse the files it contains, though (but only "plain" files, i.e., not nested archives).
Fl is highly customizable, and mimics Xedit/Kedit/THE sets of commands quite closely. In fact, many of its commands descriptions were snarfed from THE documentation. (THE is "The Hessling Editor", available from: <URL:http://hessling-editor.sourceforge.net>.)
Installing Fl is very simple: just copy FL.CMD somewhere along your PATH, REXXVIO.DLL somewhere along your LIBPATH and, if you want to use a profile file, customize PROFILE.FL and move it somewhere along your DPATH.
If REXXVIO.DLL is currently in use, close ALL your OS/2 windowed or fullscreen sessions, and open a bare OS/2 windowed session (that is, one not starting CmdShl or Fl). You can then replace REXXVIO.DLL from this session.
If you were using a previous version of MLRXSHL, execute the following code from an OS/2 command prompt, to allow the new functions defined in REXXVIO to be registered:
rexxtry call VioDropFuncs
If you want to enable the minimal ZIP archive support, you have to install the UNZIP32 library somewhere along your LIBPATH. You can obtain this library in the Info-unzip package. If you use an old OS/2 release that has no support for long files (i.e., files that are bigger than 2GB), overwrite REXXVIO.DLL with REXXVIO.OLD beforehand.
Syntax
fl [filespec] [([tree|sort[d|a] name|ext|size|date [...]]]
Parameters
(Noprofile - Do not use a profile file; (Profile file - Use the specified profile file; (Sort[d|a] opt - Sort the entries by opt; (Wide - Display more than one file per line; (Tree - Recursively include subdirectories.
Examples
fl c:\os2 (sort name fl *.cmd fl
The Fl screen is composed of four parts. The first line is the info area. It is followed by the main area. The penultimate line is the command area, while the last line is the key/message area.
The Info Area
It contains the directory name, the available space in the corresponding disk, and the current file # and file count.
The Main Area
This area is composed of two sub-areas. The first one is the prefix area. It is by default filled with "="s. You can replace them with line number, by issuing the "SET NUM ON" command in the command area. The second one contains the file's information; that is, file date, file time, file size and file name.
The Command Area
Use this area to enter non-file related commands (such as, say, PSTAT, SET NUM ... or RESET PREFIX). The number surrounded by square brackets is the current view number (1 for the first opened directory, 2 for the second, ...).
The Key/Message Area
This area usually displays function keys labels. If an error occurs, it will temporarily display an error message.
When entering commands in the main area, you can use the following shortcuts:
/ = The whole file name (drive+path+name+ext); /n = The file name; /e,/t = The file extension (or "type"); /p = The file path; /d,/m = The file drive (or "mode"); /o = Nothing; // = A "/" symbol; " = Repeat the previously defined command.
If you enter a main area command without at least one of the above shortcuts, the complete file name will be added at the end of the command (so, use the "/o" shortcut if you do not want to pass the file name to the command).
For command area commands, these shortcuts refer to the current file. Additionally, the complete file name is NOT appended by default.
The following commands are also available in addition to all standard internal or external commands:
select and display restricted set of lines
SYNTAX
ALL [rtarget]
DESCRIPTION
The ALL command allows for the selective display, and editting (subject to SET SCOPE) of lines that match the specified target. This target consists of any number of individual targets seperated by "&" (logical and) or "|" (logical or).
For example, to display all lines in a file that contain the strings "ball" and "cat" on the same line or the named lines .fred or .bill, use the following command:
ALL /ball/ & /cat/ | .fred | .bill
Logical operators act left to right, with no precedence for &.
ALL without any arguments, is the equivalent of displaying all lines in your file.

If the cursor is positioned on the left or right edges of the screen, the cursor moves to the left or right edge of the screen on the same line.
CURSOR [ Escreen ] UP | DOWN is similar to CURSOR Screen UP | DOWN | LEFT | RIGHT, except that where scrolling of the window is possible, then scrolling will take place.
CURSOR CMdline moves the cursor to the indicated column of the command line.
CURSOR HOME moves the cursor to the first column of the command line (if not on the command line), or to the last row/column of the filearea if on the command line.

execute a macro command file
SYNTAX
MACRO filename [arguments]
DESCRIPTION
The MACRO command executes the contents of the specified filename as command line commands. The filename can contain either a series of Fl commands, or can be a Rexx program. The filename is considered a macro.
Rexx macros can be passed optional arguments.
COMPATIBILITY
In a macro file, you can use any REXX instruction, but, due to the current implementation, it must fit in one line. That is, you can use:
if foo = 'XYZZY' then say 'Nothing happens'; else x = x + 1
But you cannot use:
if foo = 'XYZZY' then
say 'Twice as much happens'
else
x = x + 1
Alternatively, you can use the comma as a line continuation marker
foo = 'Hello',
'world'
Another important difference with standard REXX scripts is that you cannot call Fl commands in a REXX structure using the standard way. You have to use the execute function. That is,
if answer = 'YES' then
'DEFINE F12 OSNOWAIT shutdown'
else
'DEFINE F12 TEXT shutdown'
does not work. You have to use:
if answer = 'YES' then
call execute 'CMDLINE', 'DEFINE F12 OSNOWAIT shutdown'
else
call execute 'CMDLINE', 'DEFINE F12 TEXT shutdown'
[But it works just fine outside of a structure.]

DESCRIPTION
The first form of the SET PREFIX command allows the user to display the prefix area and optionally to select the position were the prefix should be displayed.
The second form of the SET PREFIX command is functionally the same as the first form. The difference is that when the prefix area is displayed with SET NUMBER ON, numbers are displyed with leading spaces rather than zeros; with SET NUMBER OFF , blanks are displayed instead of equal signs.
The third form, turns the display of the prefix area off. Executed from within the profile, the only effect is that the defaults for all files is changed. Executed from the command line, the SET PREFIX command changes the current window displays to reflect the required options.
The first and second forms of the SET PREFIX command allows the user to specify the width of the prefix area and optionally a gap between the prefix area and the filearea. m can be specified as an unsigned number between 2 and 20 inclusive. n can be specified as an unsigned number between 0 and 18, but less than the number specified in m.

TAG /ball/ & /cat/ | .fred | .bill
Logical operators act left to right, with no precedence for &.
TAG without any arguments displays all lines without any highlighting.
If SET HIGHLIGHT is not set to TAGGED, then if the specified rtarget is found, SET HIGHLIGHT is set to TAGGED.
