* /help spawn Qh if possible, else issue a Usage message
*
* Revision History:
* 08-Jan-1990 SB SLM version upgrading added; Add CopyRightYrs Macro
* 03-Jan-1990 SB define QH_TOPIC_NOT_FOUND
* 20-Dec-1989 SB Add check for return code of 3 for qh
* 14-Dec-1989 LN Update Copyright to include 1990
* 23-Oct-1989 LN Version no bumped to 1.01
