Hi all,

 

I have several macrovariable named:

&mAA
&mAB
&mBA
&mBB
...

Each of them has a string value.

 

Now I create a macro with two arguments 

mymacro ( firststring, secondstring)

I want this macro to be able to modify the current value of one of my macrovariable with the value of secondstring.

Which macrovariable need to be modified? That's the point:

 

The value of the firststring can be "AA","AB","BA,"BB",...

If it is AA I need to modify &mAA

If it is BA I need to modify &mBA

 

Globally I need to do

&m&firststring.. = &secondstring.;

But like this of course, it is not working, and I don't really know how to do it?

 

Do you have an idea?

 

Thanks

You'll need to construct a %LET statement to assign a value to a macro variable.  The contents of your macro might end up looking like this:

 

%let m&firststring = &&m&secondstring;

 

Or, it might end up being:

 

%let m&firststring = &secondstring;

 

It's not clear which result you are looking for (probably the second one, based on your sample attempted code), but both of these are somewhere in the ballpark.

It's indeed the second one. Sorry if I was not completely clear.

 

Thanks very much for the answer! 🙂
