INPUT

58) INPUT (Input from Digit Keys)

Function: INPUT waits for a 0 - 9 digit code, and then modifies the program execution
sequence.
Argument
[Integer]
Explanation: INPUT puts the player into Input Mode, where it waits indefinitely for one
of the 0 - 9 digit codes. The digit code is usually generated as the result of a viewer's
pressing one of the digit buttons on the RCU. This is often a response to a "menu" of
choices displayed on the video screen.
The command's argument is normally a single digit "N" (1 - 9). High-order digits, if
present, are ignored. If the argument is missing or 0, the value 9 is used for N. The
argument allows a separate block of code to be executed for each of the N "expected"
viewer inputs - the codes for the digits 0 through (N-1). The other digit codes (N - 9) are
treated in one single category, as "other digits". For example, when N = 3, each of the
responses 0, 1, or 2 causes its own block of code to be executed. The "other" entries
(codes for the digits 3 through 9) are not ignored - they cause the player to skip over the
three reserved blocks of code and continue program execution.
While waiting for this numeric input, the player does not accept most other "commands"
from the RCU. REJECT, HALT, AUDIO1 and AUDIO2, and various Transmit commands
are exceptions.
When digit M's code is received, if M < N, the player skips M blocks of code. Otherwise, N
blocks are skipped over. Then, program execution continues. For each block, code is
skipped until exactly one BRANCH is skipped.
The following table shows the relationship between argument values, "expected" input
digits, and "other" digits.
