In one of my program I am getting steps like :

GHPD&TYPE.03 DC C'T'
DC AL3(1)
DC A(2)

I am well aware about addresses like

DC A(SCITY-SDATES)

Where SCITY and SDATES are variables in a copybook but what is the sense when constant is inside the ACON and length of ACON is also altered.

It is an easier method of creating a 3 byte literal. Compare these two examples to get the same thing:
Code:
ONE   DC    AL3(3)   
TWO   DC    X'000003'
