Hello: I have a data file where one of the columns contains full path names. Is there a trick to getting a basename from that field? Any builtins for other transformations on that field? Appreciate any pointers. Thanks, Sarat.

Recursion: ;)
basen(fullp) = (a = strstrt(fullp,'\'), a == 0 ? fullp : basen(
substr(fullp,a+1,strlen(fullp) ) ) )
pr basen('helo')
pr basen('helo\halo')
pr basen('helo\halo\holo')
In the same way you can delete (possibly multiple) .extensions from
the filename.

Can you use a function?
e.g. f=system("basename ".fullpath)
