OS/2 UTILITIES


This product is not public domain. It is
distributed under a Share Wear License. If you
like this software and find it to be of value, a
nominal contribution of $5 is appreciated.
For $20, users will be supported and informed of
updates. For $25 users will be informed of changes
in the source code and the code will be made
available to them. These utilities are different
than some in that most of the source code is
provided. Providing the source code insures
the user of virus and bacterium free code. Your
financial support of this package will insure
continued updates and improvements of this code
as well as development of other packages that
contain full source code in the future. You are
encouraged to distribute these utilities.

All of the programs included (and source code)
were developed on a Compaq 386/20 using the
Microsoft C compiler version 5.1 with OS/2
v1.0 and 1.1 .

All of these programs will run with the
presentation manager.

I hope you find these utilities useful and
informative.

These utilities are for use with OS/2. Some of them may work in DOS if you
BIND them using the bind program. Where problems arise in binding, they will
be noted.

Summary:

Program Function

DD.EXE Delete directory and all subdirectories beneath the specified one.
This one actually works (source file:DD.C). If you bind this
program, in DOS, the directory cannot have any subdirectories.

HEX.EXE Converts hexadecimal integers to decimal integers (source
file: HEX.C)

LF.EXE Locate file: finds location on all files on drive matching the file
specification (source file: LF.C)

MES.EXE Leaves a block message on the screen. The more lines per screen you
computer is set up to handle, the longer message you can leave.
(source file: MES.C)

NO.EXE Exception handler. Based on popular DOS program.
(source file: NO.C)

RN.EXE Rename directory. (Can also be used to rename file.) (source file:
RN.C)

SC.EXE Screen color. Sets screen color. You may need to install the
ANSI driver: ANSI.EXE . (source code: SC.C)

SIZE.EXE Gives actual files size, diskette file size and hard drive file
size of file spec. Very useful for determining how much space
taken up in a directory. (source code: SIZE.C)

SM.EXE Set mode to either 25, 43, or 50 lines per screen (depending on
your video card) (source code: SM.C)

WFRE.EXE Gives total disk space, space available, space used and

Description:

DD.EXE Delete directory.

format: dd directory name.

directory (normal, hidden, read-only, system), all
directories beneath the specified directory and all file
beneath the specified directory. If you bind this program,
in DOS, the directory can have no subdirectories.

HEX.EXE Hex to Dec converter.

format: hex hex-number [hex-number] [hex-number] . . .

example:
hex 4df 8ef ffffffff 0 2135f

4df h = 1247
8ef h = 2287
ffffffff h = 4294967295
0 h = 0
2135 h = 136031

The designator 'h' refers to the hexadecimal number.

LF.EXE Return all locations of file matching the file spec.

format: lf [d:] [file spec] [/Switches]

Switches
/E Display .EXE type

examples:

lf - find all files on the disk
lf me.* - find all me.* files
lf ? - print help message
lf prog.? /e - find all prog.? files with their type

Important: This program is just a shell to make use of
the OS/2 WHERE.EXE program. YOU MUST HAVE THE WHERE
PROGRAM IN YOUR PATH OR THIS PROGRAM WILL FAIL.
