And - as a suggestion - as mentioned earlier - the array of file names should contain ACCOUNT-FileName to ensure MainAcct-CustFile # TestAcct-CustFile -- it's happened more than once the DIM'd array of file handles survived a LOGTO and suddenly that person is trashing the MAIN account data thinking they are in the TEST account.
We have a DIM(50) of file handles we carry around - I'm sure we could do 200 -- you're limited by the OS open files, but at the point you approach that, U2 usually 'soft closes' the file (closes at OS level, but remembers your handle and reopens on demand). > > > > Is there anyway I can open the file once (in the subroutine) and > > thereafter use the same file handle (to avoid opening the file each > > time the subroutine is called) ? > > > > All the code on this site opens the file in the calling routine and > > passes the handle to the subroutine. > > > > I want to rather make the subroutine a stand-alone, not > requiring more > > than the subroutine call added to the calling programs. > > > > I have a suspicion I can use named common - if so, does > this have to > > be declared in the calling routine (which would negate my purpose!). > > Yes - I use this approach and it works fine.
