Not Closing Channels in Subroutines.

Not Closing Channels in Subroutines.

Not Closing Channels in Subroutines.

When I open a file in a subroutine (by getting a channel which is free) the channel number (eg. 20) is "in use" even when I come out of the subroutine. This happens when I do not close the channel in the subroutine?

The problem is that if the subroutine is called a number of times then I am slowly running out of channels and when the limit of 256 is reached my mainline program aborts.

Ideally when I come out of a subroutine shouldn't the passed parameters be the ones that I should be bothered about?

The others variables should automatically get cleared/initialised.


RE: Not Closing Channels in Subroutines.

Why don't you close the channel before RETURNing
from the subroutine.

If the subroutine is called alot, open the file in
the mainline housekeeping routine.
