'Assigned' does not work as expected

[Jerry Thomas]

I have subroutines that have optional parameters.

Code: Select all

GoSub>Test,,3

SRT>Test
  Assigned>Test_Var_1,bRslt
  If>bRslt=TRUE
    //do stuff
  Endif
End>Test

In the Watch List, Test_Var_1 shows as blank but bRslt=TRUE.

I have tried using

Code: Select all

Length>Test_Var_1,varLength
If>{(%varLength%>0) and (%varLength%<10)}
...

but this can be cumbersome.

Any suggestions?

Something like this help?

Code: Select all

GoSub>Test,,3

SRT>Test
  If>%Test_Var_1%<>{""}
    //do stuff
  Endif
End>Test

See HERE for a similar issue and answer.

Definitely cleaner than what I was doing.
Thanks!

Assigned tests for whether the given variable name EXISTS. Since you can see it in the watch list it DOES exist. Hence you get true.

As JRL suggests it looks like you actually want to test whether or not the variable is an empty string.
