* {{Parameter|longVariableOrLiteral&}} is converted to four ASCII characters. To see this in action, try {{InlineCode}}PRINT MKL$(12345678){{InlineCodeEnd}}.
* The numerical data usually takes up less bytes than printing the [[LONG]] number to a file.
* [[LONG]] integer values can range from -2147483648 to 2147483647.
* Since the representation of a long number can use up to 10 ASCII characters (ten bytes), writing to a file using [[MKL$]] conversion, and then reading back with the [[CVL]] conversion can save up to 6 bytes of storage space.
* [[CVL]] can convert the value back to a [[LONG]] numerical value.
* [[LONG]] numerical variable values [[PUT]] into a [[BINARY]] file are automatically placed as an MKL$ [[ASCII]] string value.
