Finding line sequence problems
Use the SEQUENCE compiler option to find statements
that are out
of sequence. Breaks in sequence indicate that a section of a source
program was moved or deleted.
About this task
When you use SEQUENCE, the compiler checks the
source statement numbers
to determine whether they are in ascending sequence. Two asterisks
are placed beside statement numbers that are out of sequence. The
total number of these statements is printed as the first line in
the diagnostics after the source listing.
