Has anyone successfully passed a scratch (or file) array to a global function?

It seems to be broken here (version 5.5).

Global function has parameters:

    PARAMETER                                    VARIABLE       ARRAY
    SEQ    TYPE              VARIABLE NAME              TYPE    LEN  SIZE 
    ---  ---------  --------------------------------  --------  ---  -----
    001      E      $_ARRAY                              A        2   100

which can reference the array and GENs fine.


Calling function has interface:

 SEQ TYPE            PARAMETER                          MAP TO             
  --- ---- -------------------------------- --------------------------------
  001  E   $_ARRAY                             $_ARRAY

And logic 000:

LNE  ST -----------------------  S T A T E M E N T --------------------------
 001     DEFINE $_ARRAY(100, 2)

And logic 010:

007     GLOBAL_LSCALL(GLOBFUNC,INTF)

I've tried parameter type 'I', 'O' and 'B' and also using '$ARRAY()' in place of '$ARRAY' in the interface.

Mostly I get:
057 - INVALID USE OF SUBSCRIPTED VARIABLE - $_ARRAY

If I use $_ARRAY() then the function GENs but doesn't call the global function.


Any help?


Thanks,

Tony.

Tony,

We never got it to work either... (going back to 4.6 as well).

hth,

From one that I'm changing right now, although it's in a B&T call....

Global Update parms:
Parameter Variable Array
Seq Type Variable Name Type Len Size
+++ ---- ============= ---- --- ----
010 B $ERROR.CODE() A 2 60
011 B $$ERROR() A 80 60


Update that calls it, interface parms

Seq Type Sz Parameter Map To
--- ---- -- --------- ======
010 B A 2 $ERROR.CODE() $ERROR.CODE()
011 B A 80 $$ERROR() $$ERROR()

Have the arrays DEFINE'd in both functions

HTH
Rick


Edit: this is v5.5 r517, HPUX 32-bit

The 'E'xternal parameter is used for FILE variables so you do not have to define a file within a function. The documentation strictly states this. I have never used it for scratch arrays and don't know why you would want to. It must work but it is not PRO-IV's intended use. Scratch arrays are entered as parameters with brackets as two previous replies show. We have been passing scratch and file arrays in parameters successfully in ver 5.5 for quite a while and it works fine.

Thanks very much.


Could've spent ages trying all the possibilities, very depressing when you don't even know if it is possible.
