[Gretl-devel] checking the status of "set" options

Hi, below is a hansl function that checks whether shell calls are enabled, by scanning the output of "set" for the line " shell_ok = 1". <hansl> function scalar checkshell(void)     string setbuf     outfile --buffer=setbuf         set     end outfile     strings setparts = strsplit(setbuf, "\n")     return nelem(instrings(setparts, " shell_ok = 1")) # mind the leading blank! end function </hansl> This could be generalized, but the whole thing strikes me as relatively complicated. I have the feeling we discussed this before, but I don't remember any details. What's the best way to query the currently active set options programmatically? thanks sven
