Re: NEC-LIST: Help with error message.

Hi Peter,

I sent your email to our NEC core programmer and here is his reply:

****
    This model becomes an out of core run since MAXMAT is set at 7000
(less than 9600). This type of error usually results from not having
enough space left on the drive that has to contain the files that
support the out of core run. One way to get around the error is to
force these temporary files to be written to another drive by providing
an additional argument to the core, this argument being a path
indicating where the files should be written to.

   That RECOT in the error message indicates that the error resulted in
subprogram RECOT which meant (in the old days) RECord Output to Tape.
****
Another option is to increase MAXMAT to 9600 and ensure you have enough
virtual memory to run the model completely in core.

Regards,

Joe
