0809 -
080901 - Follow up ref SDS 2 4W8F.
080902 -
080903 - Over the next couple of days, made a major improvement to the menu
080904 - system by eliminating cut and paste for managing screens.  This
080905 - continues prior work over the past five (5) years eliminating cut and
080906 - paste from SDS code, because it works differently from other SDS files
080907 - in a way that has adverse impacts on memory and program reliability.
080908 - Tried several design schemes and finally settled on a method that
080909 - reduced the size of the code considerably.  An added benefit of this
080910 - change is to reduce memory and recover some compiler space, so there
080911 - is room to do other things.

081304 -
081305 -    On 021014 eliminated using cut and paste in the subject report
081306 -    system. ref SDS 2 4W8F
081308 -  ..
081309 - Decided to change the design of the menu system that up until now has
081310 - used cut and paste to control screen changes.  On 030920 developed a
081311 - different system using the copy and move commands to replace cut and
081312 - paste for managing menu screens. ref SDS 1 XR5K  This saves memory,
081313 - and further stabalizes the program.
081315 -  ..
081316 - The new system using copy and move commands, reduced code requirements
081317 - by about 40%.  After creating the new system with copy and move
081318 - commands, was able to refine the code by using a scheme with repeat
081319 - and delete commands instead of copy and move, and this reduced the
081320 - code by nearly 80%.  This saves memory, improves program speed,
081321 - increases reliability and reduces maintenance.  Additionally, seem to
081322 - have recovered about 2K of compiler space.
