[comp.sys.mac.hypercard] Writing XCMD/XFNC - A short help please?

shani@TAURUS.BITNET (12/11/88)

I have to write an XFNC, and my book (the hypercard handbook) says to little
about this subject. Can anyone help?

Can you please send me (shani@Math.Tau.Ac.IL or shani@taurus), a short
example of an XFNC so I can see ho it recives parameters and how it returns
answer. I prefer something wich is written for Lightspeed-C, but Tourbo-Pascal
is okay too. I also unerstand that the XFNC should be added to the resource
fork of the Hypercard program itself, how exactly? what name and type should
it have?

AdvThanksance

This is in response to a couple of requests for help on XCMD's and glue
files.  The information that you need is available from APDA.  It is called
HyperCard Developer's Toolkit.  Their address:

APDA
290 SW 43rd St.
Renton, WA 98055

There is also a book called XCMD's for HyperCard (MIS Press) that contains
example XCMD's and XFCN's.

     publisher: MIS Press, Box 5277, Portland OR  97208
     $24.95
The book covers both XCMD's and XFCN's.
