16F1827 table not behaving as expected

[Bruce]

You can save a ton of code space by not including all the zeros in the upper section. Give this a shot.

Measurement var byte
dacdwell var word
dacdwell = 0
 
main:
  FOR Measurement = 0 TO 253    ' 254 total entries
      IF Measurement < 128 THEN ' all values with an index < 128 are 0's
         dacdwell = 0
         GOSUB Show
      ELSE
         GOSUB DwellTable
      ENDIF
  NEXT Measurement
 
FIN:
  GOTO FIN
 
DwellTable:
IF Measurement > 191 THEN DwellTable2
