I have a code snippet that uses -strpos-, and works correctly within Stata GUI, but within an ado file doesn't seem to work. Within the Stata GUI, I tried

---
. local typelist "byte int long float double"
. forvalues i=1(1)244 {
.       local typelist "`typelist' str`i'"
. }
. local type = "int"
. local typegiven = strpos(`"`typelist'"', `"`type'"')
. display `"`type'"'
int
. display `typegiven'

Within the ado file, I wrote

---
program define myfunc, byable(onecall) sortpreserve

gettoken type 0 : 0, parse(" ")
local typelist "byte int long float double"
forvalues i=1(1)244 {
        local typelist "`typelist' str`i'"
}
local typegiven = strpos(`"`typelist'"', `"`type'"')
display `"`type'"'
display `typegiven'

end
---

When I ran the ado file in the Stata GUI, it returns the first display lines correctly, but doesn't seem to return anything from the second display line (or may be returns a blank.

---
. myfunc byte test
byte

Can someone help me with this code?

Many thanks.
