QNX2 Ed Question

Dear Colleagues,

I have a QNX2 ED question. I am editing a file of about 45k in size. I
suddenly hit a bump where I can no longer add any more text to this file. I
get Error messages, something about “out of memory”.

Does anybody know what the maximum editable file size for QNX2 Ed is??

Karl

I can’t recall the exact limit, but since ‘ed’ was compiled with the
old small-model QNX 2 compiler, and the maximum file size it could
handle was very limited.

When the Computer Innovations compiler was released we made a large
data version of ‘ed’ called ‘bed’ (big ed). This is available from
QUICS (ftp.qnx.com) under /usr/free2/eds/.

bed can be invaluable, but it be aware it doesn’t handle signals
(qnx2 exceptions) well. If you try to record a keystroke macro,
for example, it will croak.

Thanks dood!

Ed can only handle up to 64K of data. This includes its stack and
working variables. The exact file size will depend on the average
length of a line in the file. Longer lines == more data. This is
because there is some per-line overhead.
