Perhaps a little explanation is in order here.
There are no global variables in u2.
Thus the need to pass the variables to the subroutine.
If you have truly global variables - used in many subroutines - you could
put them in a common block.
( add a line
COMMON /name/ REC, VAR
in every program that use them )
If the program stays as simple (small) as it is now a gosub is neater
than an external
routine:
...
read x from y else null
gosub sub
...
sub:
print ...
return
...
end

Hi
You need to pass REC as a parameter to the subroutine see below:
