----------  Set  or Unset  ----------

"Set" is a command as well as a keyword in several other  commands,  including
"insert", "select", and "update".

For further information on these commands, enter:

                help insert;
                help select;
                help update;

The "set" command deals with variables.

Syntax:

     set | from FILE           |
         | [all] [|into| FILE] |
         |        |onto|       |
         | VARIABLE [to] VALUE |
         | VALUE {, VALUE}     |

Specifying "set" by itself prints out all  non-standard  variables  and  their
values,  as  well as system variables with non-standard default values.  Using
"set all" prints out all variables.

The output of a "set" command may be redirected into a new file or appended to
an existing file by specifying "into" or "onto", respectively, and a filename.

Using "from FILE" allows the setting of variables, which of  course  are  con-
tained in the file FILE.

Variables may be assigned values using "set VARIABLE to VALUE".  If the  VARI-
ABLE already exists, its value is changed to VALUE.

The numeric variables "1" through "99" may be assigned values in  order  using
"set VALUE {, VALUE}".

For further information on variables, enter:

                help variables;

To remove or unset an old variable, the "unset VARIABLE" command is used.

Syntax:

     unset VARIABLE;

VARIABLE is the variable to be removed.

To show the value of a variable use the SHOW command.

Syntax:

     show VARIABLE { , VARIABLE};

For further information on this command, enter:

                help show;
