c Date munger function
c part of DTC

	Subroutine datmun(line)

	byte l1,l2,l3
c
c function:
c  edit a line starting with a date of form
c mm/dd/yy
c into one starting with a date of form
c mmddyy
c
c also if the line starts with a date of form
c dd-mmm-yy
c edit back into mmddyy from
c that form. Leaves whatever follows the date alone.
c Added for DTC to not have to use such a crock date
c format as the original; too hard to use otherwise.
c  if mmddyy form already exists, leave line alone.
