[comp.sys.mac.programmer] How to correctly install a VBL

dewhirst@kuhub.cc.ukans.edu (06/27/91)

Could a kind soul send me some Pascal code that installs a VBL?  I've read the
Tech Notes and IM and have tried different approaches for the past couple days. 
My guess is I'm not setting and restoring A5 correctly.  My interrupt routine
doesn't move memory - I simply set a global to TRUE.

I could post the code if anyone thinks it would help.

Thank you.
