New in ZSLIB version 2.1
                          02 Feb 90 by Carson Wilson

The most important change in version 2.1 is that the PRDATx and MDATx routines 
no longer check for a valid datestamp.  Instead, they assume that the caller 
has already verified the BCD stamp with a call to ISBCDD.  This not only saves 
code, it is also more intuitive than having a separate (and inferior) date 
validity routine in each PRDATx and MDATx module, and allows the routines to 
use fewer registers, since no return codes are needed.  My apologies for any 
inconvenience this causes.  Several other routines have also been reduced in 
size, thanks to suggestions from Howard Goldstein.

The empty module ZSLIBVER was added as a means of identifying which version of 
ZSLIB a .REL library contains.  The version is the last two digits of the 
public symbol "VERSxx" which is contained in the ZSLIBVER module.

Finally, SMHL5DC+ was inoperative in ZSLIB version 2.0, resulting in faulty 
time storage for relative ("+nnnn") times.  This has been fixed.
