Answer / chaitanya
If we need a value of a macro variable then we must define
it in such terms so that we can call them everywhere in the
program. Define it as Global. There are different ways of
assigning a global variable. Simplest method is %LET.
Ex: A, is macro variable. Use following statement to assign
the value of a rather than the variable itselfe.g.
%Let A=xyz x="&A";
This will assign "xyz" to x, not the variable xyz to x.
