Hi,
Some things that come to mind:
Even if you do need an EXE, don't use it, but use something diagnostic instead, e.g. FREQ.
Use DATASET rateher dan SAVE for intermediate files.
If you use a DO IF structure, startt evaluating the most common category, e.g. DO IF (brd EQ "sparrow"), ELSE IF (bird EQ "penguin"). (Boolean shortcircuiting)
Use CACHE if you read data on a network share multiple times.
Make your data no longer and wider than you need (e.g. discard records and vars you won't use).

Hi Guys...
One simple question, can you give me some advice, many some do´s and dont´s in order to speed up the execution of my SPSS sintax... I know it´s not a good idea to use to many EXECUTES commands because it drastically reduces the speed of a program...
But I would like some other tips and recommendations...
