Basic Examples  (1)

Convert a string to a stream:

Wolfram Language code: str = StringToStream["234,32412,4234"]

Read the first number from the stream object:

Wolfram Language code: Read[str, Number]

Read the next character from the stream:

Wolfram Language code: Read[str, Character]

Close the stream:

Wolfram Language code: Close[str]

Possible Issues  (1)

If a string contains special characters, the Byte format can return values greater than 255:

Wolfram Language code: string = "aαℵ";
Wolfram Language code: stream = StringToStream[string] ReadList[stream, Byte]

These correspond to the individual character codes:

Wolfram Language code: ToCharacterCode[string]

Close the stream:

Wolfram Language code: Close[stream]
