[ncl-talk] Joining large files using "cat" option

[Mary Haley]

Amit,

[Sorry, I forgot to cc ncl-talk on the previous message.]

We are a bit puzzled by the "File too large" error. We believe this is a
UNIX error that is indicating your file is too large to be written on your
system.

Do you have some kind of quota limit on the size of files you can write?
Or, are you by any chance running on a 32-bit system?

What is the size of "pr"?  You can do a "printVarSummary" on pr to get this
information.

--Mary
