You need to put braces {} around global names so Stata can tell where they end -- local don't have this problem because they include `' to enclose the full name.

Local variables can act as prefixes and suffixes in variable names:

local a = "local"
gen `a'_x = 1 // create local_x
gen x_`a'= 1 // creates x_local

global b= "global"
gen x_$b= 1 // creates x_global

gen $b`a'= 1 // creates globallocal

My question: Can I create something a variable named "global_x" using the global variable $b ?
