How to replace the GOTO statement in COBOL without changing
the structure of program. e.g. consider following code...
I.D.
E.D.
D.D.
P.D.
compute C = A + B.
GOTO para 100-display.
compute D = C - D.
GOTO 200-display.
some other logic......
........
GOTO 300-para.
......
......
GOTO 400-para.
Now I want to replacce all GOTO statements without
changing the structure and otput of program.

Answer / muttaiah
My Opinion is we won't be able to change GOTO with Perform
here. why because if we use perform instead of goto like
this..
compute C = A + B.
Perform para 100-display.
compute D = C - D.
Perform 200-display.
what will happen means once c value is calculated. It wil
execute 100-display para once it completes. It will
calcualte d value. which is not the case in goto. Once C
value is calculated the control is passed to 100-display
para. The control will never return and cal D value.
what say!!
Correct me if i'm wrong please

Answer / suraj borge
Using evaluate statement
take the value of para in a variable then evaluate it for ex.
evaluate xyz
when 100 perform para-100
when 200 perform para-200
..

like that we can replace the goto statement .

Answer / krishnan a
Instead of GOTO we can use PERFORM noneed to go EVALUATE
also
compute C = A + B.
PERFORM 100-display.
compute D = C - D.
PERFORM 200-display.
some other logic......
........
PERFORM 300-para.
......
......
PERFORM 400-para.
