Wrapper for mkdir that allows you to create a whole new path, not just a single directory. It also traps and reports errors generated by mkdir.

This is more useful than the builtin mkdir function that will throw a runtime error if the full path to the new directory does not already exist.

Usage:

string makeDir(string dirName)

Example:

string errors = ""
errors = makeDir("C:\\Temp\\tom\\dick\\harry")
print errors "\n"

Source code:

//  makeDir
