[ncl-talk] sub: Second do loop

[Rick Brownrigg]

Hi Dale,

I looked a few days ago at your original posting on this issue, and didn't
have a good solution to offer. The issue at hand is that each time through
the outer do-loop, the call to asciiwrite() completely overwrites the
contents of the file written during the previous iteration. This is by
design of the asciiwrite() function, for better or worse. That means you
either need to provision an array to collect all of the results you want
written and make one call to asciiwrite() at the end of your do loop. Or I
suppose there are some system/shell tricks you could employ, like writing
to a temporary file, during each iteration and then using NCL's system()
function to concatenate that to your accumulative file using I/O
redirection each time through the loop (e.g., cat temp
>>myIntendedOutputFile).   Not particularly elegant, but that would work.

Hope that helps...
Rick
