There are much ways to restart a program.

RESTART= ({* } [,checkid] )
({stepname } )
({stepname.procstepname} )

1)If the job got failed in JES2 system.this will restart the program from the beginning.

//SORTVBFL JOB SORTVBFL,(SORTVBFL),CLASS=A,MSGCLASS=A,NOTIFY=&SYSUID
Restart=Y

2)If you want to Restart a particular step in JCL.
just use RESTART=STEPNAME(i.e Step040)

3)if you want to restart a particular step in proc
Use RESTART=procstepname.STEPNAME

*****************JCL*************************************
//SORTVBFL JOB SORTVBFL,(SORTVBFL),CLASS=A,MSGCLASS=A,NOTIFY=&SYSUID
//JCLLIB JCLLIB ORDER=(AAAA.BBBB.CCCC)
//JCLPROC EXEC JCLPROC
.
*****************JCL*************************************
.
****************PROC*(AAAA.BBBB.CCCC)***********************

//JCLPROC PROC

//STEP10 EXEC PGM=iefbr14
//.....
//.....
//STEP20 EXEC PGM=
//.....
//.....


if you want to restart at step020 of proc

Code RESTART=JCLPROC.Step020 on the JCL

4)//WORK JOB ,PORTER,RESTART=(*,CKPT2)
//SYSCHK DD DSNAME=CHKPT,UNIT=3330,DISP=OLD

checkid :-

Specifies the name of the checkpoint at which the system is to restart execution. This checkpoint must be in the job step specified in the first subparameter.
Omit checkid to request restart at the beginning of the specified job step.

When the name contains special characters, enclose it in apostrophes. Code each apostrophe that is part of the name as two consecutive apostrophes. For example, code CHPT'1 as 'CHPT''1'.

The JOB statement indicates that the system is to restart execution at checkpoint CKPT2 in the first job step. The SYSCHK DD statement defines the data set on which the system wrote checkpoint CKPT2.
