Michael,

Your right let me clear this up , its really two classes i'm having issues 
with ,

TReader is only missing ReadStr - i have replaced the call with readstring 
as for the readvalue seems ok it now compiles OK. - readvalue exists in 
TReader
TWriter is only missing WriteStr & WriteValue ( which replaced WriteStr with 
writestring seems to compile ok ) and for writevalue , i just did the follow 
write(byte(vaCollection),1)\

is it me or should WriteValue exist in TWriter since a ReadValue Exists in 
TReader ?

The other part i've found missing is for TWrite is writepropname which 
basically writes a string containing the path and classname , but since you 
can get the path via PropertyPath i've just done a write string with it and 
the classname

Cheers , at least with this i've learnt how to compile the source code of 
the RTL ( basically i got the fpcsource2.2.4 and did it from the ground up 
and got it working with lazarus - i'm using 2.2.4 because i need to be able 
to debug under x86_64.)

Justin
