 I've set up **two** data files : ''REGS'' and ''CHESS'' in extended memory and made **two** version of the simple program above, the only change is to alter the lines which put the name of the file in ''ALPHA''
+Then I thought of adding a 7th Register holding the ''DATE'' of the latest ''SAVE'' for the ''CHESS'' statistics, so I can keep track of whether I'm up to date in entering the scores.
+Delete the original ''CHESS'' Data File & make a new one with 7 registers
+  * ''ALPHA'' -> ''CHESS''
+  * execute ''PURFL''
+  * ''X'' = ''7''
+  * ''ALPHA'' still -> ''CHESS''
+  * execute ''CRFLD'' to create the new 7-register data file
+The date is automatically stored in the register just //after// the ''Stats'' - in general in ''R18'' when ''ΣREG'' is ''12'' - and automatically adapts the register used depending on ''ΣREG?''
 Here is ''SAVEC'' and ''GETC'' for save''C''hess and get''C''hess
