Simple question of memory vs. speed. At 4k, I'd go the variable
route. You could also build an array as you import, as that may make
it easier to parse through on a line by line basis.

Well, better question would be whether it makes any sense. Repeating
MvIMPORT is certainly no problem, but it is rather inefficient and slow. I
cannot imagine any reason for importing the same file in the same scrip more
than once.

I'd tell that better would be parsing the needed information from the file
in a single pass, or storing the MvImported file into a variable, or into a
database. Instead of the slow MvImporting it again, you would then only
parse the data already available in the variable (or database)

Just an FYI - yes, it can be done.
Good ol' MvWhile.
