Others noted the main difficulty. 

The example here may not be the real problem. Even if it isn't, 
the alternative solution of generating the contents
of such a list by a loop is worth noting. 

forval i = 1/50 { 
	local list "`list' `: di %02.0f `i'"
} 

That is, the little twist here of leading zeros is soluble 
by an in-line format.
