place in the syntax chart where the next token could be either a dataset name or
a number. For instance, if the parser encounters a step boundary and the next
few characters are:
Then a reasonable parser can conclude we are attempting to define a dataset
named 12345678. There are good reasons to forbid variable names from beginning
with digits (that is why 0C4X cannot be coded C4X), but those reasons do not
apply to dataset names.

The hexadecimal constant 0C4X is a number, but could be confused with a
name if names could start with digits (which they can't, only letters
and the underscore).
