CHARDEF Statement

CHARDEF is an optional statement with many parameters for tailoring the data structure diagram. If your printer's character set does not include characters that are specified by default, use the CHARDEF statement to substitute print characters that are available to draw the diagram.

For example, in the default format, all arrows pointing to the left are drawn with a less-than sign ( < ). If this character is not available, you can use the LARROW (left arrow) parameter to specify a character to take its place. You can also change the print characters to achieve a different graphic effect.
