Figure B–1: Format of the character attribute table

The CODEPAGE keyword signals the start of the table entry. The CODEPAGE-NAME keyword precedes the name of the code page the character attribute table applies to. A code-page name cannot exceed 19 characters and can consist of the characters A–Z and a–z, the numerals 0–9, and the dash (-). The TYPE keyword tells OpenEdge whether the code page is single byte or multi-byte. For single byte, TYPE is 1. The ISALPHA keyword signals the start of a character attribute table. A value of 1 means the corresponding character is alphabetic; a value of 0 means the corresponding character is not alphabetic.

To build a character attribute table for a single-byte code page, provide 256 values in 16 rows of 16 values each. Be sure to format the rows of data exactly as shown.

The ENDTABLE keyword signals the end of the character attribute table. The ENDCODEPAGE keyword signals the end of the table entry.
