Datasets are concatenated by writing a normal DD statement
for the first dataset and then adding a DD statement without
a DDNAME for each dataset to be concatenated in the order
they are to be read. The following is an example of three
datasets concatenated:

//YEARDAT DD DSN=JAN.DATA,DISP=SHR

// DD DSN=FEB.DATA,DISP=SHR

// DD DSN=MAR.DATA,DISP=SHR

Datasets are concatenated by writing a normal DD statement for the first dataset and then adding a DD statement without a DDNAME for each dataset to be concatenated in the order they are to be read.

Example:
//STEP1 EXEC PGM=PGM1
//DD1 DD DSN=TSTA.CHAN.PS1,DISP=SHR
// DD DSN= TSTA.CHAN.PS2,DISP=SHR
// DD DSN= TSTA.CHAN.PS3,DISP=SHR
