Hi All,

I have used a rexx program
ADDRESS TSO
"ALLOC FI(DD1) DA('Input dataset') SHR REUS"
"ALLOC FI(DD4) DA('Output dataset') SHR REUS"
"EXECIO * DISKR DD1 (FINIS STEM A."
SUM = 0
DO I = 1 TO A.0
J.I = SUBSTR(A.I,55,10)
SUM = SUM + J.I
END
"EXECIO * DISKW DD4 (FINIS STEM J."
SAY 'SUM' SUM

But my dataset is having the first and the last record as the header and trailer record.

Can I skip the first and stop before last in this Rexx program.

Thanks
Shri

Hi Shri,

Yes you can Skip Header and Trailer Records with simple change in your program.

ADDRESS TSO
"ALLOC FI(DD1) DA('Input dataset') SHR REUS"
"ALLOC FI(DD4) DA('Output dataset') SHR REUS"
"EXECIO * DISKR DD1 (FINIS STEM A."
SUM = 0
/*-------------------- Code Replaced from here */
Count = A.0 - 1
DO I = 2 TO Count
K = I - 1
J.K = SUBSTR(A.I,55,10)
SUM = SUM + J.K
END
/*-------------------- Code Replaced till here */
"EXECIO * DISKW DD4 (FINIS STEM J."
SAY 'SUM' SUM

I guess this would serve your purpose.
