Selecting Local Or Host Macros; Deleting A Macro Definition - Tektronix 4106 Operator's Manual

HOW TO CREATE MACROS
SELECTING LOCAL OR HOST MACROS
Normally, when you press a programmed key, the macro defined for that key is sent
to the host computer - just as if you had entered that sequence of characters on
the keyboard. This allows you to avoid typing a sequence of commands you
frequently use with your host.
However, you might want a macro to be interpreted as a sequence of commands to
the terminal (rather than the host). For instance, if you frequently use a particular
sequence of commands to change a terminal characteristic - like , the size of the
dialog area or size of your hard copies - you could program a key to execute that
sequence of commands. In a case like this, you do not want the macro sent to the
host, but you do want it executed by the terminal.
To construct a macro to be executed by the terminal, you must include a pair of
key-execute characters at the beginning and at the end of the macro. The default
key-execute character is
oL,
which you type as Ctrl-P. (If you need to use the
0 L
character within a macro , you'll need to change the default key-execute character
- see the SET KEY EXECUTE CHARACTER command description in your
41061410714109/CX Programmers Reference Guide .)
The key-execute character acts like a switch that sends the contents of the macro
either to the terminal or to the host. The first time the key-execute character
appears in the macro , it switches to the terminal. The next time it appears in the
macro , it switches back to the host.
DELETING A MACRO DEFINITION
You can delete a macro and return a key to its default meaning by reissuing the
command you issued to create the macro - either LEARN or NVLEARN. In
response to the prompt, press the key that contains the macro you want to delete,
then press F1 . If the macro has been saved in nonvolatile memory (that is, created
with the NVLEARN command and followed by an NVSAVE), you would also reissue
the NVSAVE command.
For example , to delete a macro that was assigned to the F6 key and was saved in
nonvolatile memory, put the terminal in Setup and enter:
NVLEARN
The terminal responds with its prompt:
Press the key to be defined :
Press the F6 key, then press the F1 key. The F6 key is now back to its default
meaning . (With the exception of the function keys, the keycap label of a key
identifies its default meaning .)
Finally, issue :
NVSAVE
