[comp.sys.mac.programmer] Help! SetPortBits works on MacII not SE?

cpyang@ccnysci.UUCP (Chao Ping Yang) (04/15/89)

I wrote a DrawVerticalString routine that uses an
offscreen bitmap. I found my routine works on 
MacIIs bot produce garbage on SE and Mac+, namely
non-color Macs. The only thing that I suspect causing
this difference is SetPortBits, or CopyBits, since these
are the only places a BitMap or a PixMap makes a difference.

Can somebody help me out on this?

I am using MPW 2.0 and C 2.01, maybe I should use 3.0?
