st: Using scalars when defining matrices

[Rachel <academicgirl@gmail.com>]

I'm having trouble with the syntax of matrix define (or input) when
using scalars.  When I try the following:

scalar b3=2
matrix input Matrixnew=(1,`b3',`b3',`b3'\ `b3',1,0,0\ `b3',0,1,0\ `b3',0,0,1)

I get a syntax error even though I've put a space in between the
slashes and the scalars (per the manual) to avoid confusion.  What am
I doing wrong?

Thanks,
Rachel
