Tongue in cheek comments aside, you would also need to enclose the called macro as -di `a'- in order to have Stata evaluate the macro. If what you wanted to do was display the contents of the macro (rather than evaluate the macro) you would have to nest it in double quotes -di "`a'"- much as Maarten explained earlier.
