search_keyword ( : : ProcName : Keywords )

How to call keywords which are assigned to procedures.

The operator search_keyword returns all the keywords in the online-texts corresponding to those procedures which have the indicated substring ProcName in their name. If instead of ProcName the empty string is transmitted, the operator search_keyword returns all keywords. The keywords of an individual procedure can also be called by using the operator proc_info. The online-texts will be taken from the files english.hlp, english.sta, english.num, english.key and english.idx, which are searched by HORUS in the currently used directory and in the directory 'help_dir' (see also get_system and set_system).
