Syntactic ordering: The operands of the `resmatch-command' and `atomatch-command' must be specified in the given order, except for the PRINT option in the resmatch-command.

The `coor-spec' is a file specification for coordinates. See Read Syntax, for the detailed syntax.

The `non-bond-specs' are described in Non-bonded Syntax.

The `hbond-specs' are described in HBOND Syntax.

NOTE: The syntax above requires that single delimiters sometimes be placed next to double delimiters. In this case, be sure to leave a space between the single delimiter and the succeeding double delimiter. $ $$ is OK; $$$ or $$ $ is not.
