"test21" README
===============

Source: node.c errexit.c

Desc:	"node.c" tests the reading of 31 empty datasets in random order;

Invoke:	load [0] node.rx [/cfs/ctape0 [TEST01]]

Note:	* use tape that is created by "test22"
	* "test21.sh" calls "node.rx" 
	* log is on "test21.SLr0" 
	* result is on "test21.SRr0" 
	* tape will not be unloaded after the test because of the 
	  undocumented "set_tapedev" statement

Algo:   * read valid datasets in random order
	* read datasets with invalid setting to verify to have read error
	* read datasets with wrong dataset seqeunce numbers to verify error    
	* the total number of empty datasets is 31
	* JMAX = 2 and IMAX = 101
	  UEXITRET = 1 (value to return when user exit is called) 
 	  VERIFY = 1   (set verification to TRUE so that the dataset being
			read is verified)
	  ZEROREAD = 1 (set to check the length of empty dataset to be zero)
