How to count the number of macro variables in use?

[Emjay]

I'm defining a variable number of macro variables that I want to use later in my program.

The number of those user-defined macro variables will also be a parameter later.

So let's say:

%let Opt1= 'abcd' 'efgd';
%let Opt2= 'abascd' 'efgretd';
%let Opt3= 'abgfcd' 'eqqwfgd';
%let Count_Opt=3; /* I don't want to do this manually. */

Is there a way to write those variables in a list and count this number then?

The only thing I found was the

%put _user_;

statement to see all my defined variables but this writes to the log only. And even if I could manage to acces this list, I need to somehow just get that variables that start with "Opt".

Is there a way or do I have to stick to manually defining this number?

THe list is in the Dictionary table, which you can access and count.

SASHELP.VMACRO is the name of the table.
