Re: Call a C program from RPG with variables & a return

Buck,
I have tried the dcl-s bignumber Float(8); in my RPG program but keep getting:"An assignment operator is expected with the EVAL operation. "
I thought I traced it down to PTF SF99701 which needed to be at release level 26 or higher, but after loading release level 37 I still get the same message.  Any suggestions?  Thanks. Regards, Stephen M. Mooney

Charles,
Thank you for your suggestion.  I was using the SQL set function after calculating the total for three months:
$Tot03 = ($AvgH(1) * $AvgH(2)  * $AvgH(3))

SET :$Geo03  =  :$Tot03 ** (1/:$Root03); 

And that works fine.  When I try it with 12 month's, the result field is not large enough (set to 63P) and the program errs.  Same happens with:
$Tot12 = ($AvgH(1) * $AvgH(2)  * $AvgH(3) *                      $AvgH(4) * $AvgH(5)  * $AvgH(6) *                      $AvgH(7) * $AvgH(8)  * $AvgH(9) *                      $AvgH(10) * $AvgH(11)  * $AvgH(12))                    ** (1/12);
I think I need to use 'C' because if I declare the result field as "double" I do not have the restriction I do in RPG.                                Regards, Stephen M. Mooney

RPG supports double as dcl-s bigNumber float(8);
