ON KEY GOSUB
Chapter 2 Program Instructions
Field of Application Statement for branching to a subroutine when a specified key on the
printer's front panel is activated.
Syntax ON KEY()GOSUB|
↔
is the i.d. number of one of the keys on the printer's front panel
(see illustration below).
/ is the number or label of the line to which the program will
branch when the specified key is pressed down.
Remarks All Intermec Fingerprint 7.2 compatible printer models are fitted with a
membrane keyboard. Each key can be enabled individually using its i.d.
number in a KEY ON statement. Then the key can be assigned, alone or in
combination with the key, to make the program branch to a
subroutine using an ON KEY... GOSUB statement. The key adds
100 to the unshifted i.d. number of each key, as illustrated below.
Please note the difference between the i.d. numbers of the keys and the ASCII
values they are able to produce (see e.g. BREAK).
Note that BREAK takes precedence over any ON KEY statement, provided
that break interrupt is not disabled for the "console:" by a BREAK 0 OFF
statement.
