2.2.3 Extending the example

Here's how we could change the example program to define another procedure:

PROC main()
  WriteF('My first program')
  fred()
ENDPROC

PROC fred()
  WriteF('...slightly improved')
ENDPROC

This may seem complicated, but in fact it's very simple. All we've done is define a second procedure called fred which is just like the original program--it outputs a message. We've called this procedure in the main procedure just after the line which outputs the original message. Therefore, the message in fred is output after this message. Compile the program as before and run it so you don't have to take my word for it.
