RE: data structre as parm

Mike,

You have QAHSTDS and, implicitly, its basing pointer pQHASTDS defined
outside the procedure, so they are global.  Inside the procedure you
have defined the pointer pQAHST00.  This is the pointer that you fill
with the address of the parameter, but that does nothing for your global
pointer pQHASTDS.  So when you try to use fields from QAHSTDS, the
basing pointer is not set and you get a pointer error.  When you change
the name of the local variable pQHAST00 to pQHASTDS, you still have a
problem.  By defining a local variable pQHASTDS, you hide the global
variable with the same name.  So the pointer of the data structure is
still not set.  Remove the local definition of pQHASTDS and you should
be fine.

Well I'm going to open this back up, because I'm still lost.
I have the procedure compiled.  Blows up on the run telling me ' Pointer
not
set for location referenced'
So my calling program looks like this

Callp   gemail(QAHSTDS)   looks good here.

Procedure here.

 D QAHSTDS       e ds                  ExtName(QAHST00) Based(pQAHSTDS)
  * __________________________________________________


P GEMAIL          B                   EXPORT

D GEMAIL          PI
D QAHSTDSp                            LIKE(QAHSTDS)

D pQAHST00        s               *   Inz


D EMAIL           S              1



c                   Eval      pQAHST00 = %Addr(QAHSTDSP)

C/EXEC SQL
 C+ SELECT QPEMAIL INTO :EMAIL  FROM QACTL00 WHERE QPCODE =
 C+ :QHCODE
 C/END-EXEC

Blows when executing the SQL.   QPEMAIL is a field from the data
structure
QAHSTDS.

QAHST00 is an externally described file.
