There are many INFILE/INPUT features. Most of them aren't too hard to
understand in isolation. Their interactions can be tricky.
A couple of things in your test program are odd in the sense that they
cause features to work at cross purposes or disable one another:
1. Using the "&" modifier when a space is not one of the delimiter
characters. Try
delimiter=' !'
2. Not using the ":" modifier for variable NAME. Try
name : & $60.
