81# The PDB file format is fixed-field, 80 columns. From the spec:
82#
83# COLS        DATA
84#  1 -  6      "HEADER"
85#  11 - 50     String(40)
86#  51 - 59     Date
87#  63 - 66     IDcode
88#
89# Thus, positions 7-10, 60-62 and 67-80 are spaces. The Date must be in the
90# format DD-MMM-YY, e.g., 01-JAN-70, and the IDcode consists of numbers and
91# uppercase letters. However, examples have been seen without the date string,
92# e.g., the example on the chemime site.
