REXX program to show words that may be produced from a phone number

This illustrates the use of REXX arrays/compound variables.
/*phonetso        tso version */
/* Displays the letters corresponding to a telephone number.
    You can see if a phone number spells anything interesting.
      To execute:

     Example of executing with telephone number 5552345 (max 7 digits):

    phonenum 5552345

    Also writes the letters to a file named Nphonenumber TEL
          for example: N5552345 TEL
    You can print, edit or view the file


   When Address() = "TSO" then nop
   When Address() = "ISPEXEC" then nop
   When Address() = "ISREDIT" then nop
Otherwise  signal Not_on_TSO
