Folks,

Figured out the problem. I did not know how VARCHAR2 stores values.
Unlike a CHAR variable, Oracle does not store the trailing blanks. So,
when I tried to select against a CHAR I did not find a hit. I defined 2
VARCHAR fields in my program, trimmed out the trailing blanks and used
it my host variable.

 D ITEM            S             25A   VARYING      
 D HIBC            S             25A   VARYING      
 C**************************************************
 and 
   EVAL      ITEM = %TRIMR(PSMFG#)   
   EVAL      HIBC = %TRIMR(PSAITM)   

Regards,

Ravi
