short variable names in V14 of SPSS

Okay, there must be a way to do this, but I can't find it! I've got hundreds of syntax files which are now - because V14 allows (by default) variable names longer than the 8 character limit it used to have - broken. I can't bring myself to go back and fix them all to handle longer variable names (it would take weeks of doing nothing else!).

Does anyone know where the magic button is to push (or better still magic syntax code to run) which restricts a run of V14 to 8 character names?
