Good morning to all:
I am having an ongoing problem in R:Base (6.5++ for Windows) that is driving
me bonkers. The biggest problem I am currently having is that my programs
which use DATE variables, will sporadically throw an "Invalid date value
(2418)" error. I say sporadically because I can run a given program and it
will display this error and then I can immediately rerun the same program
with no changes in anything and the error will not appear. I have been
through my code with a fine-toothed comb and can find no plausible reason
for this. I make absolutely sure I am using a standard format and my
variables are all typed at the time of creation.
Periodically I will enter a SELECT statement at the R> such SELECT <columns>
FROM table WHERE date_column BETWEEN 09/01/2002 AND 09/20/2002 and R:Base
will complain saying Invalid date value. I can sometimes place the date
values in single quotes and R:Base is happy. The frustrating thing is that
this is not consistent. Most times it works properly other times it
complains.
Is there something I should be looking for in my code or is there something
going on with R:Base and the way it handles date values -- whether as
variables or as hard-coded values?
On another note, I run R:Base on a Windows 2000 system. I run nearly 100
programs each morning that vary from loading new data into the database to
printing out reports. It takes about 3 hours for all of the programs to
run. I can go for days and everything runs perfectly. This week, however,
R:Base is crashing every morning at various points in the morning update
routine with a Windows memory error. There are usually 3 separate messages
that you have to click through with the final result being that R:Base has
crashed. The message is to the effect that An error has occurred in RBG65
at <memory address>. Windows was unable to read the memory at address <such
and such>.
Cany anyone tell me if this is a Windows issue or an R:Base issue? I will
sometimes get a similar message when I'm running Excel.
My PC has dual 550 mhz Intel processors with 256 MB of RAM.
Any help is greatly appreciated.
Thanks
Mike Ramsour
