RunCommand module , I wrote

[okabe]

Hi,
A Christmas gift.

With minor improvements to "RunShellScript" module in ScriptMaster_16+ sample,
I have wriiten "RunCommand" module.

With a parameter "command" that cantains command and its parameters delimited by Filemaker newline
"¶" s.
, the function run the any command that can run at your computer and get the stdout strings as a return code

examle(case of widows os):
  set variable [ $a = RunCommand( "tasklist¶/nh" ) ] 
or
    set variable [ $a = RunCommand( "cmd¶/c¶dir" ) ]

I use only Windows machines, but perhaps this module will work in Mac environment
You can freely use it at your own risk.

Thank you

You can change the encode in 2nd line that you like.
