INPUT

Syntax: INPUT ["

prompt text

"] [,] [,

variable

...]

Where:

prompt text

= optional text

variable

= list of variables to assign

Function: Program pauses to receive data entered from the console input.

Mode: Run

Use: 100 INPUT "Enter batch number",$(0)

DESCRIPTION

INPUT brings in numeric and string data from the console serial port during execution. Variables are string,

numeric, or both. Variables are separated by a comma. Optional

prompt text

must be enclosed in quotes.

When an optional comma precedes the first

variable,

the question mark prompt character is suppressed and

data entry is on the same line as

prompt text

Multiple numeric data may be entered by separating individual values with commas and using <cr> on the

last one. Or, each data entry may be entered using a <cr>.

Strings must be entered with a carriage return.

If you do not enter enough data or the correct type, Basic sends the message TRY AGAIN and

prompt text

after which you must enter

all

the data. If you enter too many characters for the size of allocated STRING

memory, or more numeric values than were requested, Basic discards the extra data, emits the message

EXTRA IGNORED, and continues execution.

COM$, GET, STRING

ERRORS
