Changes since 1.2: +7 -4 lines 
Continued lines must not be interrupted by comment lines.
Such contstructs cannot be handled by the
(at best) semi-automatic compiler TAMC.
Example:

       subroutine fran(
c this is the input
     I     goin,
c this is the output
     O     goout
     &     )

cannot be handled by TAMC.
