Sub in Module not accessible

Can you post the code of the moved sub?
Looks most likely like a typo, when you moved it, the name might have changed.

this is the sub

'An NMEA checksum is calculated as the XOR of bytes between (but not including) the dollar sign and asterisk.
Sub NMEA_Checksum(sentence As String) As String
Dim s As String
Dim i As Int
Dim sum(1) As Byte

'Log("NMEA passed:" & sentence)
s = sentence.Trim

sum(0)=0
For i = 0 To s.Length-1
sum(0) = Bit.Xor(sum(0),Asc(s.SubString2(i,i+1)))
Next

'debug.print "Chk=";CstrHex(sum)
Return conv.HexFromBytes(sum)
End Sub

the name is right - i cut and paste. was zbasic code once upon a time

Did you add the modulename before the subname?
For e.g. if the modulename is 'a' you should do:
when you call it.

thanks thats fixed it

i couldn't fund this documented anywhere - where should i look ? i have the helpfinder and the beginners guide.

I dont really know the exact location
I read the beginners guide, the getting started/tutorials section of the forum and some of help viewer but I increasingly rely on the forum and forum search. I try to read every post from Erel because they are very accurate.

Check out the Documentation Wiki which says:

the module name must be added when calling a sub, such as a line in Main calling a sub (Sub1) in Mod1: Mod1.Sub1.

In addition to the information in the Wiki, it has links to the Module tutorials.
