If the first child character matches, but its additional extension characters do not match and the next child character is the same as the first, the system continues compression match processing to try to find a compression symbol that contains that child character. If, however, the next child character is not the same, compression processing uses the current compression symbol as the result. You can set up the child characters for an entry to take advantage of this processing.
If a parent entry does not have the examine child bit (CMPSCDICT_CE_EXCHILD) on for a particular child character, then the child character entry should not have any additional extension characters or children. The system will not check the entry itself for additional extension characters or children.
If a parent or sibling descriptor entry does not have the examine sibling bit (CMPSCDICT_CE_EXSIB) on for a particular sibling character, then the character entry for that sibling character should not to have any additional extension characters or children. The system will not check the entry itself for additional extension characters or children.
