Here, *GETIN is equivalent to ‘G’. The control of the program will return to the start of the main section. *CANCEL will simply end the program.

 

 

 

Label use:

 

On the ENDSR, We can mention the Label in factor-1. Suppose while we are inside a subroutine and after processing some lines we want to go directly to ENDSR, for this we can use Label as in the example below.
