Unlike the file in the previous example, some capture files may contain
thousands of status entries. As
FMT410
translates each 2-byte entry into
a 60- to 80-byte line of ASCII text, the quantity of output can add up
quickly. To alleviate this problem, the run-time flags in Table G-1 are
used to condense or eliminate portions of
FMT410
output if desired.
