FREEFORM_and_NOFREEFORM

 cDEC$ FREEFORM
 cDEC$ NOFREEFORM

 The FREEFORM directive specifies that source code is in free-form
 format.  The NOFREEFORM directive specifies that source code is in
 fixed-form format.

 The "c" in cDEC$ is one of the following:  a C (or c), !, or *.

 When the FREEFORM or NOFREEFORM directives are used, they remain in
 effect for the remainder of the file, or until the opposite
 directive is used.  When in effect, they apply to include files,
 but do not affect USE modules, which are compiled separately.

 For compatibility, !MS$FREEFORM and !MS$NOFREEFORM can be used in
 place of cDEC$ FREEFORM and cDEC$ NOFREEFORM.
