NAME
	  fglInterleavedArrays - simultaneously	specify	and enable
	  several interleaved arrays


     FORTRAN SPECIFICATION
	  SUBROUTINE fglInterleavedArrays( INTEGER*4 format,
					   INTEGER*4 stride,
					   CHARACTER*8 pointer )


     PARAMETERS
	  format   Specifies the type of array to enable. Symbolic
		   constants GL_V2F, GL_V3F, GL_C4UB_V2F, GL_C4UB_V3F,
		   GL_C3F_V3F, GL_N3F_V3F, GL_C4F_N3F_V3F, GL_T2F_V3F,
		   GL_T4F_V4F, GL_T2F_C4UB_V3F,	GL_T2F_C3F_V3F,
		   GL_T2F_N3F_V3F, GL_T2F_C4F_N3F_V3F, and
		   GL_T4F_C4F_N3F_V4F are accepted.

	  stride   Specifies the offset	in bytes between each
		   aggregate array element.

     DESCRIPTION
	  fglInterleavedArrays 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 seperately.

	  If stride is 0, the aggregate	elements are stored
	  consecutively.  Otherwise, stride bytes occur	between	the
	  beginning of one aggregate array element and the beginning
	  of the next aggregate	array element.

	  format serves	as a 'key' describing the extraction of
	  individual arrays from the aggregate array.  If format
	  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.

	  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.

     NOTES
	  fglInterleavedArrays is available only if the	GL version is
	  1.1 or greater.

	  If fglInterleavedArrays is called while compiling a display
	  list,	it is not compiled into	the list, and it is executed
	  immediately.

	  Execution of fglInterleavedArrays is not allowed between the
	  execution of fglBegin	and the	corresponding execution	of
	  fglEnd, but an error may or may not be generated. If no
	  error	is generated, the operation is undefined.

	  fglInterleavedArrays is typically implemented	on the client
	  side.

	  Vertex array parameters are client-side state	and are
	  therefore not	saved or restored by fglPushAttrib and
	  fglPopAttrib.	 Use fglPushClientAttrib and
	  fglPopClientAttrib instead.

     ERRORS
	  GL_INVALID_ENUM is generated if format is not	an accepted
	  value.

	  GL_INVALID_VALUE is generated	if stride is negative.
