That's good... I was going to suggest something else. But you got it
working...
I was thinking that this file should have a parent file... Something to
link the parent to the child.
read parent
Dow not end of parent
read child belonging to parent.
Dow not end of child
... do your work
read next child belonging to parent
enddo
read next parent
enddo.

Subject: RE: Is SQL cursor open at the job level?
I can't close the cursor, the parent thread still needs it. See below
for detail on what I'm doing:
This is what I try to achieve:
Example:
1) MYFILE has 2 fields: CHILD and PARENT.
2) If the data looks like below
CHILD PARENT
AAA BBB
CCC AAA
DDD BBB
EEE JJJ
3) This procedure basically need to return all family member back to the
caller. If say the caller pass DDD, this procedure should return:
DDDBBBAAACCC
Below is what I got (Not able to test it because when it recursive calls
the getFamilyMember, it gets the cursor already open error and the
return result become incorrect:
D getFamilyMember...
D pr 90 varying
D piMember 3 value
D MYFILE E DS
D family s 90 varying
C eval family = getFamilyMember('DDD')
C eval *inlr = *on
*************************************************************
P getFamilyMember...
P B export
D pi 90 varying
D piMember 3 value
D prList s 90 varying static
C if piMember = *blank
C return prList
C endif
C eval prList = prList+piMember+';'
C/exec sql
C+ declare c1 scroll cursor for
C+ select *
C+ from MYFILE
C+ where PARENT = :piMember or
C+ CHILD = :piMember
C/end-exec
C/exec sql
C+ open C1
C/end-exec
C dou sqlCod <> 0
C/exec sql
C+ fetch next
C+ from C1
C+ into :child,:parent
C/end-exec
C if sqlCod <> 0
C leave
C endif
C if %scan(child :prList) = 0
C callp getfamilyMember(child)
C endif
C if child <> parent and
C %scan(parent :prList) = 0
C callp getfamilyMember(parent)
C endif
C enddo
C/exec sql
C+ close C1
C/end-exec
C return prList
P getFamilyMember...
P E

Is this a SQL Procedure or RPG Procedure using SQL?
If RPG, add the HSPEC
H ActGrp(*NEW)... I believe?
