Using a 3270 terminal in 3215 mode
The z/VM® control program (CP) defines five characters as line-editing symbols. Use the CP QUERY TERMINAL command to see the current settings.
The default line-editing symbols depend on your terminal
emulator. You can reassign the symbols by changing the settings of
LINEND, TABCHAR, CHARDEL, LINEDEL,
or ESCAPE with the CP TERMINAL command. Table 1 shows the most commonly
used settings:
| Character | Symbol | Usage |
|---|---|---|
| # | LINEND |
The end of line character. With this character, you can enter several logical lines at once. |
| | | TABCHAR |
The logical tab character. |
| @ | CHARDEL |
The character delete symbol deletes the preceding character. |
| [ or ¢ | LINEDEL |
The line delete symbol deletes everything back
to and including the previous LINEND symbol or the start of the input. [is common for ASCII terminals and ¢for EBCDIC terminals. |
| " | ESCAPE |
The escape character. With this character, you can enter a line-edit symbol as a normal character. |
To enter a line-edit symbol, you must precede it with the escape character. In particular, to enter the escape character you must type it twice.
