We are trying for the multithread as well..
There are two crucial loops that run in this single program and
causing trouble.
The first loop takes round about .6ms/rec <ed: corrected from
seconds/rec> processed the other one .4ms <ed: corrected from
seconds>.
Our file is a flat file and is | delimited ..
Loop 1:
D ARRAY1 S 5 0 DIM(999)
C '|' SCAN DATA ARRAY1
C Eval X= 1
C Eval A= 0
C Dow ARRAY1(X)> 0
C Eval A+=1
C Eval X+=1
C ENDDO
Loop2:
C DOW A < #Pipesreq
C* <ed: DOW is for the> (Number of pipes actually required)
C Eval Fileds = %subst(fileds:1:%checkr(' ':Fileds)) + '|'
C eval A+=1
C ENDDO
Any suggestion will be highly appreciated..

This is what I am trying to do -
We have one control record running into multiple records of flat file
i.e.
X:01 A|B|C
X:02 D|E|F
X:03 G|H|I
X:01 1|2|3|4|5
X:02 ......
And I know that this record X:01 should contain 5 fields but have 2
missing and rest all are fine.
The output becomes like this
X: A|B|C||D|E|E|G|H|I
This whole process is repeated like this...
