Check the demo programs:

If you pass a parameter using pass by value, the passed value doesn't get affected when you change it inside the subroutine.

value = 1.

perform test using value.

write:/ value.

form test USING value(value) TYPE i.

value = 2.

write:/ value.

endform.

output would be

2

1

value = 1.

perform test using value.

write:/ value.

form test USING value TYPE i.

value = 2.

write:/ value.

endform.

output would be

2

2
