   instruction X'0000'.

   YIPXS2R is an SQLRPGLE  program having 428 lines.
I compiled the program to find out exact statement which is the cause for above 
error.

2nd level help text says below:
Message . . . . : The target for a numeric operation is too small to hold 

the result (C G D F). 

Cause . . . . . : RPG procedure YIPXS2R in program YTRPROD/YIPXS2R at 

statement 669 performed an arithmetic operation which resulted in a value 

that is too large to fit in the target. If this is a numeric expression, 

the overflow could be the result of the calculation of some intermediate 

result.
