Hi Keith,
It seems to me this should have been addressed years ago - wasn't the
Spectrum Manfacturers' thing a waste of space? IBM, holding 2 big
cards at the multivalue game, ought to be taking a lead on this, but

What is less obvious to most developers is that ON ERROR might just be
useful on a DELETE too as it is technically possible to run out of disk
space while deleting a record. (How? Think about a dynamic file
It's always annoyed me that WRITE permissions were not handled better.
Even under R83, one could set up a file with a user able to read, but
not write to it (file definition attributes 5 and 6, I think?). If a
WRITE was encountered and the permission was not correct, the program
would just crash
There is, of course, the -W compiler switch that does exactly that. Well,
warns that there is a dangling ELSE associated with a WRITE.

Be wary of ON ERROR. There are a few conditions under which ON ERROR is not
taken where I really think it should and some anomalous return values from
I personally wouldn't want that much 'power' in the write command.
Wouldn't the overhead be too intense for some of our older platforms?

Bill;
It *should* be checked on the write. From the time it's opened to the
time the write occurs circumstances might well have changed. For
example, a long running processes (like our overnight run) can start and
open files which are fine. As it runs the O/S backup routine starts to
run and
