GET variable [ , variable ] ... | Parameters | Type | Legal Value(s) | Default Value | Note(s) | | variable | String or numeric | any except reserved variable | | Type must be valid for the data that comes from the keyboard |
Data input; read a character from the keyboard (perhaps multiple times).
This statement reads single character(s), if available, from the keyboard buffer. If no characters are available, each variable is assigned 0 (if variable is numeric type) or an empty string (if variable is string type). Each item read from the keyboard (assuming a character is available) must be compatible with each variable's type. So a string variable must be specified if text is to be read. A numeric variable is sometimes used to read numeric values, but often a string variable will be used in these cases too. This is because if non-numeric characters are read when trying to input into a numeric variable, a TYPE MISMATCH ERROR is generated. A string variable will accept any character. To GET a single character, GETKEY is typically used in BASIC v3.5 or 7.0. Failure to specify at least one variable results in SYNTAX ERROR. GET may only be used as a statement in a program. Outside of a program (i.e., in direct mode) it will generate ILLEGAL DIRECT ERROR. Example (it runs so fast it will print 0 unless you have EXTREMELY FAST keyboard skills):
NEW
READY.
10 GET K
20 PRINT K
RUN
0
READY.

Example (typical for 1.0, 2.x, and 4.x):
NEW
READY.
10 GET K$ : IF K$ = "" THEN 10
20 PRINT K$
RUN
H user typed an H
READY.
