### The Prompt

The prompt is defined by the calling program. In addition, SIC modifies the prompt aspect according to the execution level. In this example the calling program is assumed to pass the string 'GAG' to SIC. Then the following prompts may appear :

            GAG>     ! Lowest execution level
            GAG_3>   ! Third execution level
            GAG_5:   ! Compile mode for the Loop buffer at level 5
