General
All defined keys are represented by either:
- A 1-byte ASCII value that is part of the 256-element ASCII character set, or
- A 2-, 4-, or 6-byte ASCII mnemonic
To represent a key defined as an ASCII character, a 1-byte ASCII value that corresponds to that character is used.
To represent a key defined as a function, a 2-, 4-, or 6-byte ASCII mnemonic that corresponds to that function is used. For example, to represent the backtab key, @B is used. To represent PF1, @1 is used. To represent Erase Input, @A@F is used. See the following lists:
| @B | Left Tab | @0 | Home | @h | PF17 |
| @C | Clear | @1 | PF1/F1 | @i | PF18 |

Note:
- The first @ symbol in the first table represents the
escape character. The first and second @ symbol in the
second table is the escape character. The @ symbol is the
default escape character. You can change the value of the escape character
using the ESC=c option of the Set Session
Parameters (9) function.
If you change the escape character to #, the literal sequences used to represent the Backtab, Home, and Erase Input keys become #B, #0, and #A#F, respectively.
Also, the literal sequence used to represent the @ symbol becomes #@.
- If you send the mnemonic for print screen (that is, either @P or @A@T), place it at the end of the calling data string.
- If you send the mnemonic for device cancel (that is, @A@R), it is passed through with no error message; however, local copy is not stopped.
