I have been called many things, clever has not been one of them

WORD size , I would think will be large enough for a day? Week? Sooner or later that will not be large enough.

So when counting you can go very large even using BYTE size. Have the count be a power of 100.

Count to 100 with VAR1. When 100 is reached VAR2 increments and VAR1 starts over.
VAR2 will have 100s and VAR1 will have ones and tens.

But get the WORD thing working
