st: matrix stack and macro (Jun Xu)

["Arthur Mu" <mystata@hotmail.com>]

One more question about matrix in ado program.

*******************************
tempname A A1
...
...
...
sum `var'
matrix `A'=(`r(mean)')
matrix `A1'=nullmat(`A1')\`A'
*******************************
The purpose of using tempnames, as we know, is to make all the names 
temporary within this program in case any naming conflict from what's left 
over before we invoke this program.  No problem with it.  However, it seems 
that the last line "matrix `A1'=nullmat(`A1')\`A'" simply not working.  I 
have tried around and found out that I have to use a real named matrix like 
A instead of the macro-referred `A' for this line of syntax to work. Is that 
true that no matter what, I have to put a matrix name, instead of a local 
macro after "\" to stack matrix?  Thanks ahead!!!
