/PAD_SOURCE D=/NOPAD_SOURCE

 /[NO]PAD_SOURCE

 Controls how the compiler treats fixed-form source code lines which
 are shorter than the statement field width (72 characters, or 132
 characters if /EXTEND_SOURCE is in effect.) This option has an
 effect on how the compiler treats character and Hollerith constants
 that are continued across two or more source lines.

 Specifying /PAD_SOURCE causes the compiler to treat short source
 lines as if they were padded with blanks out to the statement field
 width.  This may be useful when compiling programs developed for
 non-OpenVMS platforms which may assume that short source lines are
 blank-padded.

 The default, /NOPAD_SOURCE, is compatible with current HP
 Fortran and previous OpenVMS Fortran compilers, which causes the
 compiler to not treat short source lines as padded with blanks so
 that the first character of a continuation line immediately follows
 the last character of the previous line.

 If /NOPAD_SOURCE is in effect, the compiler will issue an
 informational diagnostic message if it detects a continued constant
 which may be affected by blank padding.
