APT files require at least one attribute to be defined. The attribute definition given must match the definition of the file being read. If it does not, translation is halted and the true definition of the APT file’s attributes gets logged to the log file.

The following table shows the attribute types supported.

Type

Description

char(<width>)

Character fields store fixed-length strings. The width parameter controls the maximum number of characters that can be stored by the field. No padding is required for strings shorter than this width.

date

Date fields store dates as character strings with the format YYYYMMDD.

number(<width>, <decimals>)

Number fields store single and double precision floating point values. The width parameter is the total number of characters allocated to the field, including the decimal point. The decimals parameter controls the precision of the data and is the number of digits to the right of the decimal.

logical

Logical fields store TRUE/FALSE data. Data read or written from and to such fields must always have a value of either true or false.
