Here is one way to get rid of the quotation marks:
*************
local one 1 "example", 2 "example 1"
di in r `"`one'"'
local new_one: di subinstr(`"`one'"', `"""', "",.)
di in r `"`new_one'"'
*************

Betreff: Re: ***SPAM*** st: AW: parsing problem
Tks Martin for your reply. My problem persists when I specify the
option's argument with a blank. Try the following
capt prog drop myprog
prog def myprog
vers 10.1
syntax, OPTION(string asis)
local option: subinstr local option "," " ", all
di `"`option'"'
local new_option: list clean option
di `"`new_option'"'
end
myprog, option(1 "example", 2 "example 1")
