FCONTROL(1)
When FCONTROL is used to specify a mode control
directive, an additional call to FWRITE or FCONTROL
is required if you also want to specify a carriage control
directive.
If param contains one of the mode-control directives, a
value of 0 or 1 is returned to param to indicate the
mode setting of the device prior to the call. A value of 0
indicates postspacing, a value of 1 indicates prespacing.
The default mode and carriage control is postspacing
with automatic page eject. This applies to all
Hewlett-Packard supported subsystems except
FORTRAN77/iX and COBOLII/iX, which have
prespacing with automatic page eject.
Condition Codes
CCE Request granted.
CCG Not returned by this intrinsic.
