Greetings, I've recently been working on a problem involving determining whether a given string is contained in a large list of strings. Ideally, the problem would be solved by a 'Map' function 'M' defined as M[f,{a,{b,c,d,...}}]= {f[a,b],f[a,c],f[a,d],...} For this particular problem, {a} is a stiring, and {b,c,d,...} is a list of strings, then f=StringMatchQ. The function 'M' does not appear to match up against the standard Mathematica list functions. My current solution is to 'expand' the list {a} into a list of size Dimension[{b,c,d,...}] and then use MapThread. But this does not seem particularly elegant, especially if the list is very large. Any suggestions would be most welcome! Thanks, Mark
