I have looked though the reference manuals and can't see a way to do a sort - select (first) in one pass. This is easy to do with two control steps, but was wondering if it could be done in one. To illustrate what i want - for input (eg) f1=1,1,ch; f2=3,1,ch :

2 2
2 1
1 3
1 5

i want to sort on f1,f2 ASC, and select FIRST on f1 to get :

1 3
2 1

Here's a DFSORT/ICETOOL job that will do what you asked for:

Code:

//S1    EXEC  PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG  DD SYSOUT=*
//IN DD *
2 2
2 1
1 3
1 5
//OUT DD SYSOUT=*
//TOOLIN   DD    *
SELECT FROM(IN) TO(OUT) ON(1,1,CH) FIRST USING(CTL1)
/*
//CTL1CNTL DD *
  SORT FIELDS=(1,1,CH,A,3,1,CH,A)
/*
