Calling Sequence

WriteLine(file, str1, str2, ...)

Parameters

file

(optional) one or more Maple strings to be printed

Description

• 

The WriteLine(file) command writes the specified Maple expressions to the specified file, separated by newlines, and followed by a newline.

• 

The WriteLine function returns a count of the number of characters written.  Due to different character encodings, this number may differ from the number of bytes written to disk.

• 

If file is default, the output is written to the current output stream.

• 

If file is terminal, the line is written to the top level output stream. The top level output stream is the current output stream that was in effect when Maple was started.

• 

If no strings are specified, only a newline is printed.
