The default carriage control is postspacing with
automatic page eject. This applies to all
Hewlett-Packard supported subsystems, with the
exception of FORTRAN77/iX and COBOLII/iX, which
have prespacing with automatic page eject.
Table 9-3 Selected Carriage Control Directives
Octal Code Carriage
%2–%52 Single space (with or without automatic page eject).
%53 No space, (next printing at column 1).

transfer count of 0 and the current request was
FOPEN (or HPFOPEN), FCLOSE, or FWRITE
specifying a carriage control directive of %61.
• Prespace mode: The previous request has a
transfer count of 0, and the current request and
previous request are any combination of FOPEN
(or HPFOPEN), FCLOSE, or FWRITE specifying a
carriage control directive of %61.
