LET

The LET statement assigns a value to a variable. If the variable does not exist it is created.

10 LET x = 10

10 LET name$ = fname$ +

Plain variables like x or length are always numerical, string variables like name$ always end with

a dollar sign. It is illegal to try to assign a variable of the wrong type.

LET will not create or increase the size of a dimensioned variable.

10 DIM array(2,2)

15 REM Legal

20 LET array(1,2) = 10

25 REM Illegal out of bounds

30 LET array(1,3) = 0

The form

10 LET x = x + 1

is legal. It is even legal is x has not been created (it is initialised to zero).

Usage

LET id = numeric

LET id$ = string

10 LET x = 10

10 LET x = x + 1

10 LET a$ = CHR$(13)
