how to check, if var passed by commandline to MSched exists

Hi,
i am trying to find out, how i can manage the following.

I want to allow passing serveral paramaters/variables to the script by commandline. If none of these variables were passed, the script should open with a gui. Otherwise it should run without.

The problem is, if a variable is not passed to the script, i am not able to check this. I thought, i just could use an if-statement,

e.g. IF>VAR1=""

but because the var does not exists at this time, this does not work.

Any idea? Maybe a dumb question, but i have no clue.

Regards,

Matthias

Check out the Assigned> function.

Code: Select all

//Let>variable=1
assigned>variable,result
If>result=TRUE
  MessageModal>variable = %variable%
Else
  MessageModal>variable has no value
EndIf

i knew it was a dumb question

Looked into command reference before, but some how i missed "assigned".
