The CHAR.MAP command specifies the character map to be used by the QM session on a non-ECS system.
This command, available only on a non-ECS mode system, allows a QM session to change the character map used to control sort ordering, upper/lower case pairing and character types.
When a QM session is started (login, phantom creation, etc) on a non-ECS system, the character map defined by the CHARMAP configuration parameters is loaded or, if no map is specified in the configuration parameters, a system supplied default map is used. The CHAR.MAP command can be used to select an alternative map within a QM process, for example, to meet local language conventions for character sort order.
Use of the CHAR.MAP command without a map name displays the name of the currently loaded map.
Non-ECS mode systems provide only limited support for character maps. In particular, note that changing character map may invalidate alternate key indices if the data in the file was written when a different map was in use. It may be necessary to rebuild indices.
