EEProm problem

Hi.
Have a strange problem. Need to set some default values in EEprom, but one byte is failing.
I'm doing this;
zb=0
xi=50
Writeeeprom zb,xi '"0" Key OFF
incr xi
zb=1
Writeeeprom zb,xi '"1" Key On Board
incr xi
Writeeeprom zb,xi '"1" Key On Route
incr xi
zb=0
Writeeeprom zb,xi '"0" Key On Shore
incr xi
zb=20
Writeeeprom zb,xi '"20" Current limit at 20A
incr xi
zb=1
Writeeeprom zb,xi '"1" Limit type Normal
incr xi
zb=1
Writeeeprom zb,xi '"1" Lock down

I then read back the content of the EEprom, both with the programmer, and in my program, everything is fine, except the line Limit Type Normal.. There I read the hex byte 31 which is 49 des. and asc 1.
WHY, WHY???
Anybody encountered something like this??

TYPE is a reserved word.
you better not use it.

instead of Writeeeprom you can best use the pseudo variable ERAM. Much simpler. See help : DIM var as ERAM byte

if you can not solve the problem you should show a small sample that we can actual test, thus including $regfile, etc.

I use a Eram Array for such variables.
This makes it easy to read the default as it is a variable.

If you are use to Arduino code you have to read more of Bascom's help
because Bascom does a lot of the work for you it has very powerful functions
that Arduino does not , two of note are the Split function and the Overlay

I have been programming ESP8266 with Arduino and with what I can
do with one command in Bascom takes a dozen lines of code with Arduino
