result
Array of type STRING, where the read text is stored
(call-by-reference parameter with a length of 255).
If the number of lines specified in the parameter "number" is smaller than the array length of
"result", the other array elements are not altered.
Termination of a line by means of the control characters "LF" (Line Feed) or "CR LF"
(Carriage Return Line Feed) is not stored in the target variables "result". Read lines are cut
off, if the line is longer than the string length of the target variable "result". An error message
is not output.
Note
Binary files cannot be read in.
The error message error=4: Wrong type of file is output. The following types of file are not
readable: _BIN, _EXE, _OBJ, _LIB, _BOT, _TRC, _ACC, _CYC, _NCK.
