The following DFSORT/ICETOOL job will do what you asked for:

Code:

//S1    EXEC  PGM=ICETOOL
//TOOLMSG   DD  SYSOUT=*
//DFSMSG    DD  SYSOUT=*
//IN DD DSN=...  input file
//OUT DD DSN=...  output file
//TOOLIN   DD    *
SELECT FROM(IN) TO(OUT) ON(1,3,CH) FIRST USING(CTL1)
/*
//CTL1CNTL DD *
  SORT FIELDS=(1,3,CH,A,4,8,CH,D)
/*
