[comp.sys.mac.programmer] How do I access the fields of a ParamBlockRec?

busey@milton.u.washington.edu (Thomas Busey) (05/10/91)

I'm trying to access the various fields of a ParamBlockRec,
and I don't yet have the hang of case conditioned records.
Can anyone provide code (pascal?) which would allow me to 
change the value of, say, csCode, which is part of the 
cntrlParam case condition.  

Another part of this problem involves typecoersion
of a VDPgInfo record into the csParam field of the same record.

Something tells me that the Mac should have been based on C,
and that my stupid CS101 course should have done C as well.
Thanks in advance.
