The JES2 Init & Tuna reference notes this in the description of the RANGE initialization statement:
RANGE=nnnnn[,mmmmm]|1,9999 Specifies the range of numbers (1 through 999999) which JES2 will assign as JOBIDs to jobs which originated on the local node. The integer n specifies the lowest number (1 through 999999) which will be assigned as a JES2 job identifier for jobs originating locally. The integer m specifies the highest number (n+10 through 999999) which will be assigned as a JES2 job identifier to jobs originating locally. Note that setting the upper limit above 99,999 will cause the JOBID format to change from CCCNNNNN to C0NNNNNN where CCC is either JOB, STC, or TSU, and C is J, S, or T. NNNNN or NNNNNN is a number. https://www.ibm.com/support/knowledgecenter/SSLTBW_2.1.0/com.ibm.zos.v2r1.hasa400/has2u600110.htm Greg Shirey Ben E.
