/* Illustrate use of symbolic debugger */
/* From the article "Bugs Nevermore!" by Thomas D. Webb */
/* appearing in the February 1986 issue of Computer Language */

/* To invoke the debugger, use the inkey() function and prompt the */
/* user to hit the function key F10. The program then single steps */
/* through the preprocessor T?(---) statments, which display */
/* variable values on a separate video page. Enter an F10 to turn the */
/* debugger off. Reinvoke with an inkey() call and F10 again */
