I'm in the process of converting a set of XFCN's from LSC to MPW C v3.0.

The LSC code contained inline assembly to set-up and restore the A4 register
so that global (?) strings could be used...

Something similar must be required in MPW C v3.0, but is A4 valid?  Should I
use the same inline code (code that worked under a different environment)?

Anyone have any experience with such a thing?

thanks in advance,
b.bum
