Lexical - F$EDIT
$ vbl = F$EDIT( string, keyword(s) )
Notes:
The F$EDIT() lexical function is used to modify strings.
Strings can be COLLAPSEd (all spaces and TABs are removed), COMPRESSed (spaces and TABs between words are reduced to a single space), converted to upper/lower case, TRIMmed of leading and trailing spaces and TABs, and comments can be stripped off. The comment delimiter is the exclamation point(“!”).
