Inputs a single character from the keyboard.
If data is at the keyboard, it is put in the
variable specified in the GET statement.
If no data is available, the BASIC program
will continue execution.
GET can only be used as an indirect
command.
STATEMENT SYNTAX/FUNCTION EXAMPLE
LEFT$ LEFT$ (string expression, length) 310 PRINT LEFT$(X$,I)
Gives the leftmost I characters of the string
expression X$. If I<=0 or >255 an FC
error occurs.
STATEMENT SYNTAX/FUNCTION EXAMPLE
LEN LEN (string expression) 220 PRINT LEN(X$)
Gives the length of the string expression X$
in characters (bytes). Non-printing charac-
ters and blanks are counted as part of the
length.
STATEMENT SYNTAX/FUNCTION EXAMPLE
MID$ MID$ [string expression, start [, length]) 330 PRINT MID$(X$,I)
MID$ called with two arguments returns
characters from the string expression X$
starting at character position I. If
I>LEN(X$), then MID$ returns a null
(zero length) string. If I<=0 or >255,
an FC error occurs,
MID$ called with three arguments returns 340 PRINT MID$(X$,
a string expression composed of the I,J)
characters of the string expression X$
starting at the Ith character for J characters.
If I>LEN(X$), MID$ returns a null string.
If I or J <=0 or >255, an FC error occurs.
If J specifies more characters than are left
in the string, all characters from the Ith on
are returned.
STATEMENT SYNTAX/FUNCTION EXAMPLE
RIGHT$ RIGHT$ (string expression, length) 320 PRINT RIGHT$
Gives the rightmost I characters of the (X$,I)
string expression X$. When I<=0 or
>255 an FC error will occur. If
I>=LEN(X$) then RIGHT$ returns all
of X$.
STATEMENT SYNTAX/FUNCTION EXAMPLE
STR$ STR$ (expression) 290 PRINT STR$(X)
Gives a string which is the character repre-
sentation of the numeric expression X.
For instance, STR$(3.1)="3.1."
STATEMENT SYNTAX/FUNCTION EXAMPLE
VAL VAL (string expression) 280 PRINT VAL(X$)
Returns the string expression X$ converted
to a number. For instance.
VAL("3.1")=3.1. If the first non-space
character of the string is not a plus (+) or
minus (-) sign; a digit or a decimal point (.)
then zero will be returned.
