save function; path and file name as variables

Matlabe newbie - so please bear with me. I want to use save, but make the file path and file name as variables:

MyDir='C:\TargetDir;
MyScript='RegExample.m';
*save(MyDir\MyScript)*

I've tried different variations of save, but am not able to get it to work. Any suggestions? Thanks C

This seems to work:

MyDir='C:\Dir\';
MyScript='RegExample.m';
MyFile=strcat(MyDir,MyScript);
save(MyFile)

If there's a better way, I'd be happy to know....
