We also use "xnn.meaningful.name" type labels. One advantage is that our
editor can recognise a label and putting the cursor on a line that
includes a GOSUB and pressing one function key will move the cursor
directly to the correct paragraph.
One thing I've never agreed with (except in COBOL) is "every internal
subroutine should only have on exit point" - why?
What is wrong with...
B00.PROCESS:
READ REC1 FROM file1,id1
ELSE RETURN
READ REC2 FROM file2,id2
ELSE RETURN
IF some.condition
THEN RETURN
some more statements
that actually do the work with REC1 & REC2
RETURN
The early RETURNs are just getting out of the routine on abnormal
conditions, the alternative would be to nest the code - but code nested
more than a couple of tabs deep is *much* harder to read.
