Spaces are not allowed between variables in GET_REST_VALUE and GET_DB_VALUE commands

GET_REST_VALUE and GET_DB_VALUE has the option to accept multiple variables and assign data to them, however, it doesn't allow spaces between variables(which are separated by comma). This make difficult for reading and most of the time, we adding multiple variables a good coding standard is the put a space after each comma but if we do so, the command can not be saved and give error message.
