Do you check/change accounts when you open files? Changing accts will
probably cause issues. Check FILEINFO(). Also, dimensioned arrays can be
dynamically resized b might also be helpful?
SUB OPEN.FILE.SUB(FNAME,FVAR,ERR)
COMMON /OPEN.FILES/ FNAMELIST, FVARLIST(1), LAST.ACCT
$OPTIONS -STATIC.DIM ;* redimension array on the fly
IF UNASSIGNED(LAST.ACCT) THEN LAST.ACCT = bb ;* check account b
otherwise can screw up filepointers
IF @WHO # LAST.ACCT THEN
MAT FVARLIST = bb
FNAMELIST = bb
LAST.ACCT = @WHO
END
FIND FNAME IN FNAMELIST SETTING A THEN
IF FILEINFO(FVAR(A),0) THEN ;* valid file handle
b&
END ELSE
FNAMELIST = DELETE(FNAMELIST,A)
GOSUB OPEN.FILE:
END
END ELSE
GOSUB OPEN.FILE:
END
...
RETURN
OPEN.FILE:
NEXT.POS = DCOUNT(FNAMELIST,@AM) + 1
DIM FVARLIST(NEXT.POS) ;* redimension array on the fly
OPEN b&
b&
RETURN

Subject: [U2] Need help - UV intermittent & roving file open error
I have a little file open subroutine that I use in a lot of places to
keep open files in common:
Recently (within the last two weeks) I have started getting the
following error:
[SNIP]
Program "SB1": Line 6, Read operation failure. [EBADF] Bad file number
>
Any suggestions will be greatly appreciated- perhaps the "OPEN.FILE.SUB
needs to be more robust? I suppose I could do a test read like "READ XXX
FROM FILEVAR,"TEST" ON ERROR .... " after opening the file in the
OPEN.FILE.SUB, but that doesn't really solve the problem and seems like
a lot of overhead. OPEN.FILE.SUB is embedded in a lot of places and I
really don't want to have to replace it with discrete file opens
everywhere!
