  10: **  PRINT RELATION
  11: **
  12: **	Parmv[0] through Parmv [parmc -1] contain names
  13: **	of relations to be printed on the standard output.
  14: **	Note that this calls printatt, so all the output formatting
  15: **	features associated with printatt are available here.
  16: **
  17: **	Parmv[parmc] is -1 for a "normal" print, -2 for headers on
  18: **	every page, and -3 for all headers and footers suppressed.
  19: **	err_array is set to 0 for a good relation, 1 for no
  20: **	relation by that name, and -1 for a view.
  21: **
  22: **	Uses trace flag 8
  23: **
  24: **	Returns:
  25: **		0 if no errors else the last error number
  26: **
  27: **	Diagnostics:
  28: **		5001 -- non-existant relation
  29: **		5002 -- tried to print a view
  30: **		5003 -- protection violation
  31: **
  32: **	History:
  33: **		12/18/78 (rse) -- added protection check, modified the way
  34: **				err_array was handled.
  35: **		9/12/78 -- (marc) err_array[] added, and openr()
  36: **			   call split in two to allow error messages
  37: **			   when trying to print views. error #s
  38: **			   5002 & 3 added.
  39: **		9/25/78 -- (marc) openr's merged after openr of view error
