Answer / venu

in go to the control will be transferred to either forward
or backward.once u pick to forward it wont come backward.
only single iteration will be done in go to.
in perform the control transferred to both backward n
forwars also, here multiple iterations will be done.

Answer / tata

perform is transfer control to a particular para and after
execution of that para contol comeback to the next statement
of perform.....
goto is also transfer control to a particular para and after
execution of that para contol goes forward... control never
comeback to next statement of goto......

Answer / makar

First, what are they use for?

1) 'Go to' statement is use when you want to perform a para
or skip some para's(Somtimes tag are used instead of para)
and jump to next para or tag, without the control comming
back to statement after go to. It is like a Jump.

2) 'Perform' is used when you what to want to perform a
para and want the control to comeback to called statement.
However if you do not use EXIT statement at the end of the
para, it will 'fall thru' and perform the next para. Always
use Perform.. thru and Exit statement if you want the
control to come back.

Answer / ravi

we can have control over perform but in goto we can not
have control.

Answer / praveen b

Even though i read 6 answers still have a small confusion
regarding goto.
It will be more clear if someone can explain the difference
through a piece of code.

Thanks in Advance.

Answer / jinna

Goto is unconditionally transferring the control elsewhere in the program but Perform is after execution the control return to statement

Answer / lu

goto is different than perform...goto only don't give you
any execution ...perform execute your stament.....Like
english language...
