command line parameters

[SandyDoss]

Hello,

Is there a way to accept a value into a script by running a .exe with a parameter?
How do we check if the parameter is empty?

*edit* So, after posting, my search skills somehow evolved to a point where I can actually find what I'm looking for.

I believe the answer is yes, there is a way:

Run>full-path-scriptname.exe /variable=value

This makes the variable name available to the script with the value assigned.

Run>full-path-scriptname.exe /variable=

This makes the variable name available to the script with a value of 'nothing', or 'empty'

If I'm wrong, please let me know. Otherwise, thanks for allowing me to demonstrate my blonde factor

To see if the variable exists just use the Assigned function:

Code: Select all

Assigned>VarName,VarExists
If>VarExists=FALSE
  Let>VarName=DefaultValue
Endif

So if you call your macro with:

exename.exe /VarName=fred

Then VarName is set to "fred"

But if you call it with:

exename.exe

Then VarName is set to "DefaultValue".

So there's no need to do /VarName=

But you can if you like!
