[this value here] exec "question.sqs"...

[bedges]

i've done some testing but i'm not finding the answer i seek.

i call a script which utilises _this, using [value1, value2] exec "scriptname.sqs". my question is, if i don't pass a value in one of those value fields, what will the _this return in the script?

i'm getting a "scalar bool array string 0xfcffffef" returned, but what i'm looking for is something more usable, like 'null'.

if i test for _this values in a script, do i always have to include something for the script to work with, even if it's just a null value?

The scal bool error thing means "doesn't exist, you've fucked up".

_this is an array of the parameters passed to the script by the call.    If you don't pass anything then its an empty array.

Use a count command to see how many elements there are in the array before trying to select elements that don't exist.

mmmunderstood. i'll sidestep the whole 'count' issue and use a simple 0 for blank values.
