OutputStream

OutputStream("file-name")

opens a file and returns an OutputStream.

Examples

>> f = FileNameJoin({$TemporaryDirectory, \"test_open.txt\"})
/tmp/test_open.txt

>> str = OpenWrite(f);

>> Write(str, x^2 - y^2)

>> Close(str);

FilePrint prints the file content:

>> FilePrint(f)

as:

x^2 - y^2

>> str = OpenAppend(f);

>> Write(str, x^2 + y^2)

>> Close(str);

FilePrint prints the file content:

>> FilePrint(f)

as:

x^2 - y^2
x^2 + y^2
