PowerBuilder Foundation Class (PFC) Y2K 5.0.04\6.5.1 Fixes
==========================================================
The Y2K patches are delivered as a complete set of PFC libraries (including extensions). If you are already using PFC you should replace only your main PFC libraries and not your extension libraries.

For example:
Version 5.0.04: 
Replace pfcapsrv.pbl, pfcdwsrv.pbl, pfcmain.pbl, pfcwnsrv.pbl

Version 6.5.1:
Replace pfcapsrv.pbl, pfcdwsrv.pbl, pfcmain.pbl, pfcwnsrv.pbl, pfcutil.pbl

If an attempt to fix these Y2K issues has been made by overriding these PFC functions in your own customized extension layer, first compare the official fixes with your own changes. Remove the overriding functions in your customized extension layer only if they address the fixes included in this set of Y2K patches.

For example: a Y2K issue is addressed by modifiying n_cst_datetime and overriding the function of_lastdayofmonth.  After the patches are applied, pfc_n_cst_datetime::of_lastdayofmonth now includes these changes, therefore of_lastdayofmonth in n_cst_datetime should be removed from your customized extension layer. 

After applying the Y2K patches, it is advised to perform a Full Rebuild of the application.

CR162134
Method:	of_relativemonth
