Hey everyone,
I just wanted to thank everyone for the quick responses. Coming from a
background in VB and C++, I am really trying to work at getting the syntax
of M down. Thus far, I really enjoy working with M.
Thanks again,
Eddie

Eddie / Kevin --
IO parameters in M are different for each implementation (yes, the
standard is to be different). You will have more luck with the GT.M
Programmers Guide
(http://www.sanchez-gtm.com/user_documentation/GTM-PG-UNIX44/index.htm)
in this area.

Hey all,
This is Kevin T. I am working with Eddie Hagood, who is new in our
office and interested in learning M (Great!).
We are going through some example codes, and I am having a hard time
explaining the OPEN command. We have R. Walters book, and he gives
examples like this:
OPEN 1,2:("C":"DATAFILE.TXT")
...
USE 2 READ RECORD
...
I, on the other hand, in the past have found and copied code like
this:
SET FNAME="/tmp/mytext.txt"
OPEN FNAME
USE FNAME
WRITE "TEXT OUT GOES HERE."
USE $P
I know that OPEN has LOTS of parameters, but I don't understand the
"1,2" above. Is this assigning the output file a device number or
something?
Also, how do I specify overwriting vs. appending?
Thanks
Kevin & Eddie.
