How can I control a command.com window opened by REXX?
Lee Peedin
I think RexxHide.exe may be what you need to prevent a window from
opening.
If you can't change the C program may I suggest the following to
"prevent" a window from appearing at all.
If the C code (don't know anything about C) is shelling out and
executing something like "rexx myprog.rex", then you will need rename
the rexx.exe on your system to something else and then rename
rexxhide.exe to rexx.exe
If the C code is simply shelling out as in "myprog.rex", and a command
window is opening, then your system has a file association between
Rexx.exe and your Rexx program extension (.rex or whatever). Simply
change that association to be RexxHide.exe
RexxHide.exe has been around at least since version 1.0.3 of Object
Rexx. Just be danged sure there are no "pull" statements in the Rexx
code that is being executed. It's kinda hard to respond to a "pull"
when you can't see it. :-).
If you still need the ability to resize or move, I'll have to do a bit
more research on that.
Please type the following from a command prompt:
c:\> rexx /ver
and report back the results.

How do you "call another program from REXX" from Rexx (what syntax are
you using)? I the called program another Rexx script - if not then
the RexxHide isn't any help here. I'll see what I can find concerning
sending a parameter to command.com.

I just verified that RxWinExec is available IBM Object REXX
Interpreter Version1.0.3.0
This might do it for you:
rv = RxWinExec(myprog,SHOWMINNOACTIVE)
Be sure to see the note in the documentation concerning "non-windows"
programs (you will need to edit or create a pif file for them).
In the event that you don't have the documentation loaded here it is:
-RxWinExec(-cmdline--+-------------+--)----------------------><
'-,--cmdshow--'
Runs the application as specified in cmdline.
Parameters:
cmdline
A string containing a file name and optional parameters for the
application to be executed. If the name of the executable file in
cmdline does not contain a directory path, RxWinExec searches for the
executable file in this sequence:
1 The directory from which Object REXX was loaded.
2 The current directory.
3 The Windows system directory.
4 The Windows directory.
5 The directories listed in the PATH environment variable.
cmdshow
Specifies how a Windows-based application window is to be shown. For a
non-Windows-based application, the PIF file, if any, for the
application determines the window state.
SHOWNORMAL
Activates and displays a window.
SHOWNOACTIVATE
Displays the window while the current active window remains active.
SHOWMINNOACTIVE
Displays the window as a minimized window, the current active window
remains active.
SHOWMINIMIZED
Activates the window and displays it as a minimized window.
SHOWMAXIMIZED
Activates the window and displays it as a maximized window.
HIDE
Hides the window and activates another window.
MINIMIZE
Minimizes the specified window and activates the next top-level window
in the Z order.
Return codes:
If the function succeeds, the return value is greater than 31;
otherwise, it is one of the following:
0 The system is out of memory or resources.
2 The specified file was not found.
3 The specified path was not found.
11 The EXE file is invalid.
