WRITE FIELD[#] deviceID, handle&
Use this statement to write the contents of the relocatable block specified by
handle& to the open file or serial port specified by
deviceID, in a format suitable for input by the
READ FIELD statement.
WRITE FIELD starts writing at the current "file mark" position. If first writes a 4-byte long-integer which indicates the size of the block; following this, it writes the contents of the block itself.
If you want to write only the block's contents to the file (without the 4-byte length indicator), use the
WRITE FILE statement instead:
WRITE FILE# deviceID,[handle&],FN GETHANDLESIZE(handle&)
