I have just  finished  (my  first) reading of Inside Mac Vol.  5, 
which details the  new  toolbox  routines  for the SE and Mac ][.  
These include use of the new script package, color, and other new 
goodies.

My question is this:   If  you program an application to be fully 
functional on the top of the line machine (Mac ][) which requires 
that you make use of the NEW  calls  and structures such as COLOR 
grafports, textedit Style resources, etc, HOW WILL THESE PROGRAMS 
BEHAVE WHEN RUN ON ONE OF THE "CLASSIC" MACS?

Will  it be necessary to write conditional (yuk!) code  into  the 
programs so that IF CLASSIC THEN ...  ELSE ...    or has Apple, in 
their usual tremendously successful efforts at compatibility come 
up with some method  that  these  NEW  calls will somehow operate 
in the OLD way when run on a "Classic Mac?"

Thanks.

Jeff Harrow
