Stage Variable Maximum Length

A couple of simple questions...

Is there a maximum length for stage variables? How about variables used within routines?

Thanks!

I seem to recall that the length can be quite long, but only the first 32 characters are used to differentiate.

Does this mean that if I compare two different stage variables that are 40 characters long, only the first 32 characters will actually be used in the comparison?

I'm guessing that Arnd meant the name of the stage variable.

OK - My question is actually about the maximum length of the value that may be stored in a variable.

To answer the question you didn't ask - it's something 63 significant characters to the variable name.

To answer your real question

You can keep on adding length to DataStage variables until you run out of virtual process memory. The space is not allocated contiguously, either.

Great! Thanks to both of you for the quick response!
