[Gretl-devel] some function suggestions/questions

Hi, in light of the recent discussion concerning mreverse() --for example we don't want too many different functions for doing similar things-- I would like to raise the following issues: 1) sort() and dsort(); IMHO it would be good to unify them into one function with an optional argument to specify descending sorting, like so: sort(a) or sort(a,0) : sorts ascending sort(a,1): sorts descending 2) strcmp(): would it be possible to handle this with a comparison operator like mystr1 == mystr2 and scrap the function? 3) if not, at least unify strcmp() and strncmp(), again using an optional argument: strcmp(a,b,5) would work just like strncmp(a,b,5) Actually, this looks very straightforward, or am I missing something? I'm aware these are backward-incompatible changes, so of course this needs to be carefully discussed and thought through. These are just some things I stumbled upon recently, I guess there are similar issues that could be found if done systematically. And one last thing: I may have asked this before, but having a function similar to the command 'pergm' would be useful I think. thanks, sven
