A more program space efficient way of doing ta whole heap of IFs????

OK, so let's go with Steve's idea and put it in EEPROM.

88 words.

supply_in  VAR BYTE
max_duty   VAR BYTE
ItemNo     VAR BYTE
Temp       VAR BYTE
'
supply_Max  DATA 252,250,248,245,240,237,234,231,229,226,223,220,218,215,212,210,207,204,201,199,196,193,187,0
Set_duty    DATA 154,155,156,157,159,160,161,163,165,167,169,172,175,179,181,182,184,188,191,195,214,238,251,255
'
FOR ItemNo = 0 TO (Set_duty - supply_Max)
    READ (supply_max + ItemNo), Temp
    IF supply_in > Temp THEN
        READ  (Set_duty + ItemNo), Temp
        max_duty = Temp
        EXIT
    ENDIF
NEXT ItemNo

I haven't tested it, but it looks right.
Check my work.

I originally shyed away from using suggestion, on account the initial idea provided rescued me back sufficient space, but alas, things have just got too tight, so I've just tried this latter suggestion...it worked first time & has rescued me back a good bit of space (room to breathe again!)

I'll admit I don't totally understand what's going one (other than we're storing stuff in EEPROM, then cleverly marrying it up), I'll addess my inner "huh?" demons & work this out soon, but for now I'm just chuffed the enigma works...as a bonus it's far easier for me to mate the values (the formatting on here clouds it, but it's as clear as day in reality)

Many thanks.
