+.SH PARAMETERS
+_phead(_param1)
+Specifies an index into the enabled vertex data arrays. 
+.SH DESCRIPTION
+_cmnd commands are used within _cmnd(Begin)/_cmnd(End) pairs to
+specify vertex and attribute data for point, line, and polygon
+primitives. If _const(VERTEX_ARRAY) is enabled when _cmnd is called, a
+single vertex is drawn, using 
+vertex and attribute data taken from location _param1 of the enabled
+arrays. If _const(VERTEX_ARRAY) is not enabled, no drawing occurs but
+the attributes corresponding to the enabled arrays are modified. 
+.P
+Use _cmnd to construct primitives by indexing vertex data, rather than
+by streaming through arrays of data in first-to-last order. Because
+each call specifies only a single vertex, it is possible to explicitly
+specify per-primitive attributes such as a single normal per
+individual triangle.
+.P
+Changes made to array data between the execution of _cmnd(Begin) and the 
+corresponding execution of _cmnd(End) may affect calls to _cmnd that are made
+within the same _cmnd(Begin)/_cmnd(End) period in non-sequential ways.
+That is, a call to 
+.br
+_cmnd that precedes a change to array data may 
+access the changed data, and a call that follows a change to array data 
+may access original data.
+.SH NOTES
+_cmnd is available only if the GL version is 1.1 or greater.
+.P
+_cmnd is included in display lists. If _cmnd is entered into a
+display list, the necessary array data (determined by the array
+pointers and enables) is also entered into the display list. Because
+the array pointers and enables are client-side state, their values
+affect display lists when the lists are created, not when the lists
+are executed.
