- ; Description: This module implements these routines.
- ; SetOpt1 sets input buffer size.
- ; SetOpt2 sets output buffer size.
- ; SetOpt3 sets the byte to end lines.
- ; SetOpt4 clears all tab stops.
- ; SetOpt5 sets a tab stop.
- ; SetOpt6 truncates lines to a specified length.
- ; SetOpt7 sets the left margin.
- ; SetOpt8 deletes the left margin.
- ; SetOpt9 displays a help message.
