# Paring of Fortran H Edit descriptions (Contributed by Pearu Peterson)

# These tokens can't be easily tokenized because they are of the following
|
|
# form:
|
|
#
|
|
# nHc1...cn
|
|

|
|
# where n is a positive integer and c1 ... cn are characters.

# This example shows how to modify the state of the lexer to parse
|

# such tokens
