| Answer | The system return the control from called program to the
calling program when RETURN encounter.Suppose LR is also ON
after the RETURN executed,all resources will be release.
For example,
A program pgm1 call the another pgm2 within a loop,
/free
num=0;
dow not %error;
callp(e) pgm2();
enddo;
/End-free
The pgm2 where the return is executed before LR turned ON
/free
num=num+1;
return;
/End-free
we can see the value of num will be increase all the time
when pgm1 will call the pgm2.
and opposite case:
/free
num=num+1;
*inlr=*on;
return;
/end-free
value of num will be start from zero. |

| Question |
Do all versions of the GDG have to be of the same record
length ? is it possible to ovverride the dcb of the model
dataset? |

| Answer | yes, since a GDG is defined as a flat file, with a model
DCB, it is defined with a fixed record legnth and when we
create its versions, we just add up new flat files of same
legnth of higher versions, hence they should have the same
legnth.The legnth that is there for the base (0 level GDG)
is carried forward for the next versions. |
