_phead(_param2) 
Specifies the offset in bytes between each aggregate array element.
.SH DESCRIPTION
_cmnd lets you specify and enable individual color, 
normal, 
texture and vertex
arrays whose elements are part of a larger aggregate array element.
For some implementations, this is more efficient than specifying the arrays
separately. 
.P
If _param2 is 0, the aggregate elements are stored consecutively.
Otherwise, _param2 bytes occur between the beginning of one
aggregate array element and the beginning of the next aggregate array
element.
.P
_param1 serves as a ``key''
describing the extraction of individual arrays from the aggregate array.
If _param1 contains a T, then texture coordinates are 
extracted from the interleaved array.  If C is present, color values
are extracted. If N is present, normal coordinates are extracted.
Vertex coordinates are always extracted.
.P
The digits 2, 3, and 4 denote how many values are extracted.
F indicates that values are extracted as floating-point values.
Colors may also be extracted as 4 unsigned bytes if 4UB follows the
C.  If a color is extracted as 4 unsigned bytes, the vertex 
array element which follows is located at the first possible 
floating-point aligned address.
.SH NOTES
_cmnd is available only if the GL version is 1.1 or greater.
.P
If _cmnd is called while compiling a display list, it is not
compiled into the list, and it is executed immediately.
.P
Execution of _cmnd is not allowed between the execution of
_cmnd(Begin) and the corresponding execution of _cmnd(End),
but an error may or may not be generated. If no error is generated,
the operation is undefined.
.P
_cmnd is typically implemented on the client side.
.P
Vertex array parameters are client-side state and are therefore not
saved or restored by _cmnd(PushAttrib) and _cmnd(PopAttrib).
Use _cmnd(PushClientAttrib) and _cmnd(PopClientAttrib) instead.
.P
When the _arbstring(multitexture) extension is supported, _cmnd
only updates the texture coordinate array for the active active texture
unit. The texture coordinate state for other client texture units is not 
update, regardless if they are enabled or not.
.SH ERRORS
_const(INVALID_ENUM) is generated if _param1 is not an accepted value.
.P
_const(INVALID_VALUE) is generated if _param2 is negative.
