IIN
64) IIN (Interrupt Input)
Function: This command sets up conditions so that certain external inputs will cause
the normal sequence of instruction execution to be interrupted.
Argument
[Integer]
Explanation: Unlike other Input-type commands, this command does not wait for
external input but rather tells the player to monitor external inputs while program
execution continues. Digits 0 - 9 and function keys 10 - 19 can be monitored.
The argument is used to determine which viewer inputs (0 - 19) will be monitored. If the
argument is set to N (0 < N < 21), inputs from 0 through (N - 1) are monitored. For
example, if the argument is 3, then 0, 1, and 2 will be monitored. If an argument is not
specified or the argument is set to 0, monitoring is discontinued.
When IIN with a non-zero argument is executed, the following commands up through the
next BRANCH command are skipped, With no argument or a zero argument, no
commands are skipped.
If a monitored viewer input occurs, Register 1 is set to the program address of the next
command that normally would have been executed, monitoring is disabled, the normal
sequence of program instructions is "interrupted", and execution commences with the
command immediately following the IIN command. The input's "function key" value can
be obtained with the DIN command.
Only the last IIN command remains in effect if two or more IIN commands are executed.
The other Input-type commands (IN, FIN, TIN, or FTI) also terminate monitoring.
