String Tables - Editing Strings

In this exercise, you will use the ASK1 command to edit a string from the previous exercise and to prompt the user to create new strings.
  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 WORLD                                   
 T           := ZA "20:12:07                              
 WORLDMAP    := MAP WORL 3 BOX=NO                           
 Y           := 2020231                                     
   --END OF LIST

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

  2. Change the NOTE string to read "MAP OF THE ENTIRE WORLD!"
    Type:  ASK1 NOTE
    In the pop-up window, edit the text to read "MAP OF THE ENTIRE WORLD!"

  3. Check that the NOTE string was changed.
    Type:  TL NOTE
  4. Prompt the user to input a state and a four-digit METAR station.
    Type:  ASK1 STATE 'Input a 2-character state' STATION 'and a 4 digit METAR station'
    In the pop-up window, enter a two-character state (e.g. TX) and a four-digit station (e.g. KLAR).

  5. Check that the STATE and STATION strings were added to the string table.
    Type:  TL STA
    You should see the STATE and STATION strings listed. 
     STATE       := TX               
 STATION     := KLAR
