st: while vs. forvalues

["Michael S. Hanson" <mshanson@mac.com>]

	I tried the following code snippet in a program, but I kept getting an 
"invalid syntax" error at the -forvalues- command (according to 
-trace-):

	forvalues j = 1(1)`n' {
		mat `newvec'[`n'-`j'+1,1] = `rowvec'[`j',1]
	}

When I replaced that code with the following, the program completed as 
expected:

	local j = 1
	while `j '<= `n' {
		mat `newvec'[`n'-`j'+1,1] = `rowvec'[`j',1]
		local ++j
	}

I'm puzzled by this, as my reading of p.214 of the User's Guide 
suggests these two approaches should be equivalent.  Any ideas?
