basic.mat
Assigns data to a dimensioned array.
Syntax
mat array.variable = expression {mat} array.variable1 = {mat} array.variable2
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.
