The '''&O''' prefix denotes that a integer value is expressed in an Octal base 8 format.

{{PageSyntax}} a& = &O12345671234

|
* The base eight numbering system only uses octal digit values of 0 to 7.
|
|
* Leading zero values '''can''' be omitted as they add nothing to the return value.
|
|
* Decimal values returned can be any '''signed''' [[INTEGER]], [[LONG]] integer, or [[_INTEGER64]] value so use those type of variables when converting directly as shown above. The program [[ERROR Codes|"overflow"]] error limits are listed as:
|
|
:: * [[INTEGER]]: 6 octal digits or a decimal value range from -32,768 to 32,767
|
|
:: * [[LONG]]: 11 octal digits or a decimal value range from -2,147,483,648 to 2,147,483,647
|
|
:: * [[_INTEGER64]]: 22 octal digits or decimal values from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807.
|
|
* [[LONG]] Octal values can be expressed by appending & after the number. Example: &O100000& = 32768

''Example:'' The maximum octal values of decimal value -1 in each numerical type are:
