Getting Started with  Ultrix Dec Ada

     Following these steps will get you started using Dec Ada. 

  1. Create a subdirectory for Dec Ada to use for your program library.
     It is suggested this be different from where your source resides.
     This sub directory is kept by Ada and you will mess yourself
     up if you delete anything. This is a one time action. You will get
     thoroughly confused if you have more than one program library.

       > mklib   adalib
       > amklib  adalib


  2. Add to your  .cshrc ( in your top level directory )

       > setenv ADALIB "@~/adalib"

         Then type  source .cshrc  to make it active this time.
         This is necessary because the environment variable ADALIB that
         points to your program library goes away when you log off.
         It is to easy to loose a compilation because you forgot
         to set the program library.
 

  3. Enter Ada source code with a normal editor or with the Language
     Sensitive Editor    > lse  yourfile.ada

  4. Compile using any of the these or type  > man ada

        > ada yourfile.ada     # for interactive compiling

  5. Link by using the ald command. Remember this requires
     the Ada name of a parameterless procedure. Because Ultrix
     allows long file names with underscore, please keep the file
     names the same as the Ada names. DEC uses the one variation
     on package specifications of adding an extra underscore at
     the end of the file name.

       > ald ada_procedure_name   # produces executable  a.out
       > ald -o yourfile yourfile # produces executable  yourfile

  6. An executable is produced by the link. Just type the name to execute.

       > a.out
       > yourfile

  7. For the debugger use either dumb terminal or X windows debugger

       > dbx   yourfile
       > dxdb  yourfile

  8. For more information  > cd /usr/man/man1
                           > ls a*              # to get ada related stuff
                           > ls dx*             # to get X related stuff
      > man ada    > man ald     > man amake      etc.    

  9. Source of predefined library is in:
     /usr/lib/cmplrs/ada_110/lib/adalib/_/*.adc
