handling commentsA PGN file contains embedded comments (also called annotations), which are enclosed in braces in the PGN file.
CQL can search these and write its own user-specified comments. CQL also by default adds comments indicating positions where a filter matched, and some filter-specific comments.
Filters that handle comments are:
||write specified comment|
||write squares in set associated with set_filter|
||string argument is a substring of comment of current position|
||suppress automatically generated comments associated with filter|
