MAT

Syntax	MAT array.variable = expression {MAT} array.variable1 = {MAT} array.variable2
Category	BASIC
Type	Statement
Description	assigns data to each element of a dimensioned array variable to a specific value in one operation. Array variables must be defined in a "dim", "common", or "file" statement. {mat} array.variable1 = {mat} array.variable2 Copies one array into another. The number of elements in "array.variable1" must be less than or equal to the number of elements in "array.variable2". It is possible to assign a two-dimensional array to a single-dimensional array, and vice-versa.

Example	mat customer.item = "" This sets every array element of "customer.item" to null. mat customer.item.history = mat customer.item This sets every array entry of "customer.item.history" to its corresponding entry in "customer.item". dim a(10,2) dim b(20) mat b = 1 b(3) = 2 mat a = mat b This example assigns all of the element in the two dimensional array, "a" into the one dimensional array, "b". The rows are "filled" before the columns, therefore a(2,1) = 2.
Warnings	When assigning one matrix to another, the array on the right side of the equal sign must have the same total number of elements as the matrix on the left side of the equal sign.
