What is JCL




JCL (Job Control Language)  is a language being used to submit the batch jobs on mainframe computers 
systems. Programs written in COBOL, ASSEMBLER (or) PL/I etc..can be executed on mainframe by using JCL.  


JCL Example to run program COBPROG.   

//JOB1    JOB  (034D),'RAMESH KRISHNA REDDY',CLASS='A',PRTY=6
//STEP01  EXEC PGM=COBPROG.                           <---- COBOL Program Name
//INFILE  DD   DSN=SED.GLOB.DES.INFILE,DISP=SHR
//OUTIFLE DD   DSN=SED.GLOB.DES.OUTFILE,
//             DISP=(NEW,CATLG,DELETE),
//             UNIT=DISK,
//             SPACE=(CYL,(1,5),RLSE),
//             DCB=(RECFM=FB,LERECL=70,BLKSIZE=700)
