In this exercise, you will save the strings from the previous exercises to the user-defined string table LEARN.

1. List strings in the string table.

   Type: TL

   You should see five user-defined strings (CT,KEYF4,NOTE,T,WORLDMAP) and two system strings (H,Y) as shown below.

   TL                                                                          
   CT          := ZA "#H                                                       
   H           := 20:42:30                                                     
   KEYF4       := ZA "USA   
   NOTE        := MAP OF THE ENTIRE WORLD! 
   STATE       := TX
   STATION     := KLAR
   T           := ZA "20:12:07             
   WORLDMAP    := MAP WORL 3 BOX=NO                                            
   Y           := 1999362                                                      
     --END OF LIST                                                             
   

   TL without any parameters lists the first 20 strings in the table that start with a number or a letter.

2. List all the strings in the string table.

   Type: TL OUT

   Using the OUT parameter lists all strings in the string table, including the global string, ?CROSS.

3. Save the strings you created in a string table named LEARN.

   Type: TU SAVE LEARN

   A copy of each string is saved in the user-defined string table LEARN. The strings also remain in the current string table until you delete them or restore another user-defined string table.

4. List all user-defined string tables on your workstation.

   Type: TU LIST

   You should see a string table named LEARN with your initials associated with it.

    #   NUM  SAVE NAME     INIT  PROJ  SAVED     RESTORE  USER                 
   ---  ---  ------------  ----  ----  -------   -------  ----                 
     1    1  LEARN         USER  9999  1999362                                
   

5. Delete all the strings in the string table.

   Type: TD ALL

   TD ALL removes the regular strings from the current string table, but does not remove the global or system strings.

   Also, when you saved the strings into the user-defined string table LEARN, a copy of each string was stored in LEARN and a copy remained in the string table. When you deleted the strings, they were removed from the current string table, but not from the user-defined string table LEARN.
