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           := 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. 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
