Withoutarguments, all the variables are listed, along with their memory consumptionand type. With the −v flag, the variables are listed along with their values in aformat that can be saved to a file and read back as commands. If argumentsare given as pattern , only symbols matching the arguments are printed.Such arguments may contain the ? and * metacharacters.In addition, the type of symbols listed can be controlled using the flags in thefollowing table where a − flag prevents symbols with the given attribute frombeing listed and a + flag includes symbols with the given attribute in the list.INTERIM WORK-IN-PROGRESS (8/16/01) NOT FOR GENERAL DISTRIBUTION REFERENCE MANUAL 89
