Commodore PET - Get

Format Variations
GET has other formats. but they are defective and it is not recommended
that they be used. These variations are described below.
GET may be used to fetch a numeric variable:
GET var
where:
var is a numeric variable.
If no key
has been pressed a zero is returned. However. a zero is also
returned if a zero was pressed at the keyboard. If the character returned
is not a
digit (0-9) aSYNTAX ERROR message is generated and the program aborts.
The
GET statement may have a variable list of the form:
GET var.var ..... var
where:
GET#
var is a string or numeric variable.
The Get External statement (GET#) inputs one character from an external
peripheral device
to the PET.
Format:
GET#file.var
where:
file is the logical file number that was given when
the file was opened.
var
is a string or numeric variable into which the
character is to be input.
GET# functions like the GET command except that the character is fetched
from
an external device.
GET# is valid only in program mode and only when referencing a logical file
that has been opened for input. For input from the tape cassette. PET prints the
following message
if no tape control keys are pressed when the GET# statement
is executed. Otherwise. no messages are printed.
PRESS PLAY ON TAPE #1
OK 1 when a tape control key is depressed
Example:
10 GET#4.C$:IF C$
= .... GOTO 10
