Typical Examples
WroteOK = Write(indexno, $Second)
The point '$Second' is written to the currently open file using the value of
indexno as an index into the file. Pass or fail status is stored in 'WroteOK'.
Write(2, $Second, $Minute, $Hour)
The points '$Second', '$Minute', '$Hour' are written to the currently open file
using the value 2 as an index into the file.
Note:It is advisable to use a RecordId less than 1024 whenever possible, in
order to optimise file access time (records 0 to 1023 are cached).
