LET statement

LET variable = expression

Syntax

1. let-statement = numeric-let-statement / string-let-statement
2. numeric-let-statement = LET numeric-variable equals-sign numeric-expression
3. string-let-statement = LET string-variable equals-sign string-expression

Examples

    LET A(X,3) = SIN(X)*Y + 1 
    LET A$ = "ABC"

The expression is evaluated (see 8) and its value is assigned to the variable to the left of the equals sign.
