Enhancement Request - Command variable

[Bob Hansen]

I'd like to suggest creating a new variable for the command interpreter.
Right now if you don't remember that there are multiple versions of command.com to use with Run Program, then you end up with a problem when the script is run in a different environment.

Even if you do plan ahead for multiple environments, you need to make different IF statements. It would be much easier to use a system variable in the command line.

Example:
Win 9X environment

Run Program>command.com /c find "mystring" c:\folder\myfile.txt > found.txt

Win NT environment

Run Program>cmd /c find "mystring" c:\folder\myfile.txt > found.txt

Both environments, simplified:

MidStr>OS_VER,1,2,Version
If>%Version%95,NT

Label>9x
Run Program>command.com /c find "mystring" c:\folder\myfile.txt > found.txt
Goto>More

Label>NT
Run Program>cmd /c find "mystring" c:\folder\myfile.txt > found.txt

Label>More

When doing for multiple environments, this techinque may be done multiple times, every time a Run Program uses a command line command.

With a variable for the interpreter, like OS_COMMAND, we could do something like:

Run Program>%OS_COMMAND% /c find "mystring" c:\folder\myfile.txt > found.txt

and use this in all environments.

This approach would also provide for upward growth. Example: If moving from WIN9X to XP, scripts need to be modified now. This approach would allow transport of scripts to newer OS without modifications.

Hi,

You could use the following Subroutine (just thrown together - might need a tweak) to do it for you:

GoSub>GetOsCmd
Run>%OS_COMMAND% bla bla bla

SRT>GetOsCmd
Position>95,OS_VER,1,is95
Position>98,OS_VER,1,is98
If>is95>0,Old
If>is98>0,Old
Let>OS_COMMAND=CMD.EXE
Goto>DoneCmdVer
Label>Old
Let>OS_COMMAND=COMMAND.COM
Label>DoneCmdVer
End>GetOsCmd

Was part of a VBScript I've found ... tweak it.

Set WSHShell = WScript.CreateObject("WScript.Shell")
Set WSHEnvX = WSHShell.Environment("Process")
if WshEnvX("OS") = "Windows_NT" then WshShell.run("WinNT.VBS")
if not WshEnvX("OS") = "Windows_NT" then WshShell.run("Win9x.VBS")

Thanks to support for the subroutine. It is funny, but soon after I submitted the request, I thought of the same approach.. Not using a sub routine, but just creating the OS_COMMAND variable at the beginning of the scripts.

And I keep forgetting about VB script in Macro Scheduler. Probably because I still have much to learn in that area, but examples like this help out. Thanks Lumumba for the kick toward that area.

Still would like to see a permanent variable, but work arounds get the job done. This certainly is not critical.
