Re: ***SPAM*** st: AW: parsing problem

[Federico Belotti <f.belotti@econometrics.it>]

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")
