.SH PARAMETERS
_phead(_param1)
Specifies the number of contiguous empty display lists
to be generated.
.SH DESCRIPTION
_cmnd has one argument, _param1.
It returns an integer \f2n\fP such that _param1 contiguous
empty display lists,
named \f2n\fP, \f2n\fP+1, ..., \f2n\fP+_param1 \-1,
are created.
If _param1 is 0,
if there is no group of _param1 contiguous names available,
or if any error is generated,
no display lists are generated,
and 0 is returned.
.SH ERRORS
_const(INVALID_VALUE) is generated if _param1 is negative.
.P
_const(INVALID_OPERATION) is generated if _cmnd
is executed between the execution of _cmnd(Begin)
and the corresponding execution of _cmnd(End).
