[Gretl-devel] Proposal for extra.gfn: instrings()

Hi all, quite frequently I need to scan a string array for a specific string value. Either I need just a boolean return for (non-)existent but sometimes also the entry number of string s2 in array s2. I've written two function proposals (see attached files or here: https://github.com/atecon/instrings) which may be added to the extra.gfn package if you agree. What I've called instrings_pos() [name it just instrings()] would be the more general idea though. Best, Artur
