When a program is read into memory for memory operation, comment
sections, if any, are not ignored but are also read into memory. Note,
however, that codes other than those listed in the code table in
Appendix A are ignored, and thus are not read into memory.
When data in memory is output on external I/O device(See III-8), the
comment sections are also output.
When a program is displayed on the screen, its comment sections are
also displayed. However, those codes that were ignored when read
into memory are not output or displayed.
During memory operation or DNC operation, all comment sections are
ignored.
The TV check function can be used for a comment section by setting
parameter CTV (bit 1 of No. 0100).
