Hi,
I suspect you should be using StrLen(text)+1 which gives the number of
characters in the text string (pointed at by text) plus 1 for the null
terminator.
The sizeof operator gives the size in bytes of the object you give it. In
this case you have asked for the sizeof a pointer (&text) which is 4 in
PalmOS.
