Vijay,

Easytrieve does not have the function INSPECT. How ever you can acheive the results using DO UNTIL.

The following code will strip off the leading zeroes from the 10 byte numeric field
Code:

FILE FILEIN                                   
   IN-KEY                01 03  A             
   IN-QTY                05 10  N 0           
                                             
FILE FILEOUT                                 
   OUT-KEY               01 03  A             
   OUT-QTY               05 10  A             
                                             
W-SUB        W 02 N 0                         
W-NUM-FOUND  W 01 A                           
                                             
W-STRING     W 10 A                   
  W-STR   W-STRING 1 N OCCURS 10         
                                             
                                             
JOB INPUT FILEIN                             

  W-STRING       = IN-QTY           
  W-SUB          = 1         
  W-NUM-FOUND    = 'N'       


  DO UNTIL W-SUB GT 10 OR W-NUM-FOUND = 'Y'     
     IF W-STR (W-SUB) > 0                       
        W-NUM-FOUND = 'Y'                       
     ELSE                                       
        MOVE ' ' TO W-STR(W-SUB)                 
     END-IF                                     
     W-SUB       = W-SUB + 1                     
  END-DO                 

  OUT-KEY    = IN-KEY     
  OUT-QTY    = W-STRING   

  PUT FILEOUT                                 



Hope this helps...

Cheers
