Array variables
Both numeric and character type arrays can be used at dynamic variables.
Using an array allows multiple same-type continuous data to be handled together.
Each of the array elements is referenced in accordance with the parenthesized subscript which
appears after each variable name. Subscripts may include integers or
expressions in up to 3
dimensions.
In order to use an array, Array variables must be declared by DIM statement in advance, and the
maximum number of elements which can be used is the declared subs 1 (0 ~ number of
declared subscripts).
• All array variables are dynamic variables. (For details regarding dynamic variables, refer to "11
Valid range of variables" in this Chapter.)
• The length of an array variable that can be declared with the DIM statement depends on the
program size.

Value Assignments
An assignment statement (LET) can also be used to assign a value to a variable.
• "LET" directly specifies an assignment statement, and it can always be omitted.
Format
LET variable = expression
Write the value assignment target variable on the left side, and write the assignment value or
the
expression on the right side. The expression may be a constant, a variable, or an arithmetic
expression, etc.
REFERENCE For details, refer to Chapter 8 "54 LET (Assignment Statement)"
