Ho, Dave--

    As you may remember, I posted a message to you on the IBM PCC BBS to
the effect that my REXX extended function DLL failed when compiled with
the Warp Toolkit (3.0), the one that came with the "Special Edition" of
DevCon 5.  I have devised a small test case that I send to you with best
wishes for a solution to my problem (or, at least, a suggestion as to
what might be happening, with a potential workaround)!  In the meantime,
I will stick with TOOLKT21.

The following is TEST.CMD - the test "driver."
  __________________
    /* TEST.CMD - Testing an "external function" with WarpTlkt */
    call RxFuncAdd 'BINGO', 'BINGO', 'Bingo'
    call 'Bingo' bingo
    exit
  __________________
Next, the source code for the DLL
  __________________
/* bingo.c - a test DLL for text.cmd */
    
    #define INCL_RXFUNC     /* Loads REXX "external function" type   */
    #define INCL_NOMAPI     /*   definitions and function prototypes */
    #include 
    #include 
    #include 
    #include 
    
    RexxFunctionHandler Bingo;  /* Type definition in rexxsaa.h */
    
    ULONG Bingo(                     /* REXX External Function */
            CHAR      *name,
            ULONG     Numargs,
            RXSTRING  Args[],
            CHAR      *Queuename,
            RXSTRING  *retstr)         /* Output string goes here */
    {
    
        char InputString[80];
        
        printf("We are in the external function\n");
        strcpy(InputString,Args[0].strptr);
        printf("We have read the string from Args[0]\n");
        printf("\n%s\n",InputString);
        return 0;
    }
  __________________
    And, finally, BINGO.DEF (transliterated from a "useful" DEF file):
  __________________
    LIBRARY BINGO INITINSTANCE TERMINSTANCE
    PROTMODE
    DATA MULTIPLE NONSHARED READWRITE LOADONCALL
    CODE LOADONCALL
    EXPORTS Bingo
   ___________________
     When BINGO is compiled from the command line with:
         icc /ge- /rn bingo.c bingo.def
using TOOLKT21, and run in an OS/2 window, everything works as expected.
 When compiled using the Warp TOOLKIT, running TEST blows up with an
access exception after the first printf ("We are in the...), which shows
that it never got the passed argument.  I guess I could chase further,
but I've never gotten around to learning IPMD (as you can see from the
scattered printfs in bingo.c).

    If I weren't so tired of all this, I would attempt to compile and
run the REXXUTIL sample that comes with Toolkit 3.0.  I did find out
that it wouldn't compile the REXXUTIL sample from Toolkt21 (I ended up
with an unresolved external).

    Any words of wisdom you (or anyone else) might offer will be
gratefully appreciated.  If you have no words, I will post this to the
DevCon internet address, since I don't know where else to send it.  (I
don't indulge in CIS nor OS/2 BBS; I'm paying AT&T enough, without
getting any other by-the-minute provider into the act!)

    Thanks.
