[comp.sys.mac.programmer] XFCN/XCMD Interface to Library

eac@a.cs.wvu.wvnet.edu (E Clinton Arbaugh) (10/18/89)

Does anyone have information about interfacing a function library to
HyperCard? Specifically, we are considering building an XFCN/XCMD
interface to a large in-house function library.  What I am concerned
about is limitations on global data, code size, etc. as well as just
"how do you go about doing it?"  I am assuming there will be a layer
of some sort to convert XFCN/XCMD calls into calls to our functions,
but will any modifications to the library itself be needed? And, how
does one link everything together so it can be loaded into Hypercard?
(As you guessed, I am fairly new to Hypercard.  I tried to RTFM already
but the books here don't go into much detail...)  Thanks in advance
for any light you can shed on this.
