Check to see if the fields defined in the record being passed to
GetData are the same size as the TInputLines, i.e., if an input line
is set up to read a string of up to 40 characters, then the
corresponding field in the data record should be type string[40].
Since GetData only copies the same number of bytes defined in the
TInputLine, if the first field in your data record is larger (a type
string with no size attribute is 256 bytes long), when you access the
strings after the call to GetData, they will most likely contain
garbage.
