6-6 Assignment Functions
Examples
>1 REM EXAMPLE PROGRAM
>10 LET A = 10*SIN(C)/100
>1 REM EXAMPLE PROGRAM
>10 LET A = A +1
When LET is omitted the LET statement is called an IMPLIED LET. We use the
word LET to refer to both the LET statement and the IMPLIED LET statement.
Also use the LET statement to assign string variables:
LET $(1)=“THIS IS A STRING” or LET $(2)=$(1)
Before you can assign strings you must execute the STRING [expr], [expr]
statement or else a memory allocation error occurs that causes the module to enter
the Command mode.
NOTE
The - sign used in the LET statement is not an equality operator.
It is a replacement operator. The statement should be read A is
replaced by A plus one. The word LET is always optional
(example:
LET A = 2
is the same as
A = 2
).
