The assignment operator (=) is used to assign a value to a variable. For example, if a variable first is declared as integer, the variable first is assigned to a value in the following manner: integer :: first…first = 10

and read “count becomes count plus one,” which is what is meant. So, the meaning of an assignment is something like “evaluate the expression on the right of the equals sign to produce a number and then replace the value of the variable whose name is on the left with that value.” This makes clear that a reference to count on the right side of the equals sign will use the old value. The value will not change until the very end of the statement.

The assignment statement names a variable and gives it a value. This statement can be used to give an initial value to a variable or to change its value. The equals sign (“=”) is the assignment operator in REXX. The following is a simple REXX program that uses assignment statements and demonstrates the fact that one variable can hold several different data types:

Scalar variables are binary valued or W-bit integers, for some W fixed at compile time.Arrays of binary values are allowed and may be one or two dimensional. Dimension information is specified at the beginning of the program. One-dimensional arrays of integers are equivalent to two-dimensional binary arrays with W columns.For an input size of n, we let denote the maximum number of steps required for the program to complete and denote the maximum number of bits required to represent all variables. Sahni argues that , however typically is significantly smaller.Certain variables are designated as input and used to provide input to the program at run time. All other variables are initially zero.An assignment has scalar variable or array reference on the left-hand side, and an expression on the right-hand side. A simple expression has a single operator (or is just a variable). Sparks supports a limited set of compound expressions, currently only permitting joining two simple expressions with a binary operator.Sparks supports block structured if, while, and for statements.The program terminates if it reaches a return statement, which sets a binary output variable as a side effect.
