Determine if a variable is passed to compiled script

[kpassaur]

I am trying to determine if a variable is being passed to a compiled script. The Variabe is just that variable. If it is passed I want the program to execute automatically and if not I want the user prompted.

I have tried about everything I can think of and nothing seems to work. The variable is a filename with no extension so it can be about anything.

The follow does not work and I guess I am just brain dead - as this should be very simple

If>%LoanNumber%=

and

Len>%LoanNumber%,testlength
If>%testlength%>0

Both don't work

Any ideas,

Thanks in advance

Use the Assigned> function

Assigned>LoanNumber,aresult
If>%aresult%=TRUE,continue,end

Label>continue
//Do Stuff

Label>end

Thank you I never knew of that command
