Ending SPSS syntax when a condition is met

[spssx100]

Hello

I have a fairly long piece of syntax. When running it, I want to end it immediately if a condition is met (ie somewhere in the middle).

More specifically...

If variable = value of interest , end the syntax immediately/perhaps show a message to say what's happened and do nothing else.

Can this be done?

Thanks.

NO!
You cannot do that.

I am not clear on exactly what you want to do.  If you have a block of syntax that you want to interrupt based on some criterion,  this is possible if you use Python programmability to control the flow.  You would use the spss.Submit api to run multiple blocks of code and make appropriate checks in-between blocks.  You would probably not be looking at the value of a particular case for that.

If, on the other hand, what you want to do is to interrupt the data pass in progress if some case value meets a condition, you would need to be passing the data into Python code using one of the case-by-case apis and terminate the data pass when the condition is met.  While this is quite doable, Python data passes are slower than native ones, so there would be a performance  cost.
