Assigned values can be numbers, internal variables and keywords, functions, controller parameters and
strings;
Variables hold 6 bytes of data, 4 bytes of integer (2
range of values of +/-2,147,483,647.9999.
Numeric values can be assigned to programmable variables using the equal sign.
Any valid DMC-1000 function can be used to assign a value to a variable. For example,
V1=@ABS[V2] or V2=@IN[1]. Arithmetic operations are also permitted.
To assign a string value, the string must be in quotations. String variables can contain up to six
characters which must be in quotations.
Variable values may be assigned to controller parameters such as PR or SP.
