Specify which classes of compiler commentary classes to show. com-spec is a list of classes separated by colons. The com-spec is applied to source compiler commentary if the -scc option is used, to disassembly commentary if the -dcc option is used, or to both source and disassembly commentary if -c is used. See Commands That Control the Source and Disassembly Listings for a description of these classes.
The commentary classes can be specified in a defaults file. The system wide er.rc defaults file is read first, then an .er.rc file in the user’s home directory, if present, then an .er.rc file in the current directory. Defaults from the .er.rc file in your home directory override the system defaults, and defaults from the .er.rc file in the current directory override both home and system defaults. These files are also used by the Analyzer and the er_print utility, but only the settings for source and disassembly compiler commentary are used by the er_src utility. See Commands That Set Defaults for a description of the defaults files. Commands in a defaults file other than scc and dcc are ignored by the er_src utility.
