* extract a single line of data from memory variable #2, grid along axis idim
* no error checking is done

* programmer - Ansley Manke

* V570 - reading 2nd line for bounds on a DEFINE AXIS/BOUNDS
*       *acm* 3/12 Add E and F dimensions (use nferdims in tmap_dims.parm)

* 5/15 NOTE: the newer routine EXTRACT_ARG2_LINE can probably replace this
*      and is more appropriately sensitive to argument idim
