Macro is a small programs sourcecode which we can create in
the program using DEFINE keyword,whenever we call the macro
then only it allocates memory.
In macro we can specify upto 9 placeholders which stores
the values.Eg: &1 &2 &3 &4 &5 &6 &7 &8 &9
let me explain with a simple example

Report yyy
parameters:a type i.
b type i.
data: res type i.
DEFINE hhh (here hhh is macroname)
res = &1 &2 &3 &4 &5.
write:/res.
end-of-definition.
hhh ( a + b ) (here calling macro)

in res we specified 5 place holders thats y when calling a
macro we used 5 place holders those are
1 (
2 a
3 +
4 b
5 )

this is only for eg.
in this way we can write a macro upto 9 pointers.It
shouldnt exceed 9.
