[comp.sys.mac.hypercard] Passing Variables to XCMD's

jk4i+@andrew.cmu.edu (John McCall Kingsley, III) (11/18/90)

Hi,

I am writting an XCMD/XFCN and was wondering what the value of empty is
inside the XCMD, i.e. if empty is passed in, what can it be compared to
inside of the XCMD? I am using Think C 3.0. Thanks for your help.
