eeprom command within case structure

[mjy58]

Just modified some code to save data into eeprom so it can be used between power downs and go this compiler error:

eeprom 112,(4)
^
Error: EEPROM cannot be used within If blocks

This looks fairly fatal for this construct. Couldn't find it documented anywhere, is there any way round it?

Extract of relevant code:

if verify < 14 then                
    tagno=tagposition/14+1
    select case tagno
          case 1
          .
          .                    
    end select
    select case tagno    
    case 1,3
    .
    .
                        
    case 2,4                        
    .
    .
    case 5                            
    .
    .
    case 6                        
        dfeedcountlimit = foursecs / dmotortime
        eeprom 112,(4)
        cfeedcountlimit = sixsecs / cmotortime
        eeprom 113,(6)
        high Feed                
        pause onesec            
        inctime = inctime + 1        
        low feed                
    end select
endif

The eeprom command only writes data to EEPROM when the program is downloaded - to write data to EEPROM at runtime you must use the write command. You then need to use the read command at startup to retrieve the saved value.

Thanks Nick, I had used read earlier, but somehow forgot about write
