Global Variables are declared in the block of code between the global and the input keywords, if there is an input section, and between the global and the var keywords, otherwise. The global section is optional.
global
nDate
input
// optional section
var
// declare some variables
begin
// macro body
end
Variables are declared by simply listing them in the declaration block, the same way it is done in the var block.
•You do not need to declare the type of the variables, since it is determined by the first letter of the variable name.
• Do not use any separators such as commas to separate the variable.
• Note that the list of variable can extend onto as many lines as you wish.
The specificity of global variable is that they retain their value from one execution of a macro to another.
