Hi Ed,

>} ZIP4_PARM;

First of all you need to create a structure class for a single ADDR_REC which contains all members from the typedef of ADD_REC. Then you can define ZIP4_PARM as follows:

DEFINE CLASS ZIP4_PARM AS Struct
  cMembers = "ADDR_REC o:stack"
  DIMENSION stack[10]
  PROCEDURE INIT
    LOCAL lnStack
    FOR lnStack=1 to 10
      THIS.stack[lnStack] = CREATEOBJECT("ADDR_REC")
    ENDFOR
  RETURN DODEFAULT()
ENDDEFINE

You can access memebers like this: oZIP4Parm.stack[3].cSomeMember

If you do know C/C++, you should consider writing a FLL to access these API functions that require such structures. Struct was designed to ease the use of structures for VFP developers, not to make structures fast.
