..^U:HACKER. C R O S S R E F E R E N C E.. BY RICK NASH.. I DON'T USUALLY USE CROSS.REFERENCE PROGRA MS BUT RICK NASH'S.CROSS REFERENCE IS A LIFE SAVER!.THERE IS NOT A SINGLE BASIC PROGRAM.ON THIS ISSUE THAT I HAVEN'T USE D.RICK'S CROSS REFERENCE TO DEBUG... THAT'S RIGHT! WE DO A LOT OF.PROGRAMMIN G AND DEBUGGING AROUND HERE.AND WE NEED EVERY TOOL WE CAN GET IN.ORDER TO MEET O UR DEADLINES...... SINCE CROSS REFERE NCE IS MEMORY-.RESIDENT WITH YOUR BASIC PROGRAM,.IT RUNS LIKE GREASED LIGHTNING. COMPARED TO DISK-BASED CROSS.REFERENCE U TILITIES... WHAT IS A CROSS REFERENCE .UTILITY? IT'S A PROGRAM THAT TELLS.YOU WHERE VARIABLES ARE USED AND/OR.DECLARE D AND ALSO WHICH LINES CALL.OTHER LINES. .. IMAGINE YOU HAVE A VARIABLE.CALLED S% AND SOMEHOW S% IS BEING.INCREMENTED BEYOND THE MAXIMUM.INTEGER VALUE OF 3276 7. YOU'VE TRIED.TO FIND THE LINE WHERE THIS OCCURS.BUT THE PROGRAM IS FIVE HUND RED LINES.LONG! YOU NEED CROSS REFERENC E... JUST LOAD "X-REF",8,1 AND THEN.S YS49152. THERE IS NO NEED TO TYPE."NEW" BEFORE USING CROSS REFERENCE..IT DOES A N UNNEW FOR YOU... NEXT SELECT VARIAB LES TO CROSS.REFERENCE. THE PROGRAM WIL L ASK.WHETHER OR NOT YOU WANT TO USE YOU R.PRINTER. ONCE OUTPUT IS SELECTED,.PRE SS F1 TO BEGIN THE SEARCH FOR S%..EVERY VARIABLE USED IN YOUR PROGRAM.WILL SCROL L BY. ANY LINE NUMBERS.LISTED NEXT TO T HE VARIABLE ARE ALL.OF THE LINE NUMBERS THAT CALL OR.DECLARE THE VARIABLE..... IT'S THE SAME FOR LINE NUMBERS..ANY LI NE LISTED NEXT TO A CROSS.REFERENCED LIN E NUMBER IS A LINE.THAT HAS A GOTO OR GO SUB TO THE.INDEXED LINE... KEEP IN MI ND THAT ALL THIS.HAPPENS AT A BEARABLE P ACE, SOMETIMES.TOO FAST. PRESS THE SHIF T KEY TO.PAUSE THE SCROLLING. YOU CAN P RESS.THE STOP KEY TO BREAK THE LISTING.W HILE THE INFORMATION YOU WANT IS.STILL O N THE SCREEN AND GET RIGHT TO.PROGRAMMIN G....... THERE ARE TWO ERROR CONDITIO NS.THAT MAY ARISE WHILE USING THE.UTILIT Y. IT IS UNLIKELY THAT YOU WILL.EVER SE E THEM, BUT YOU SHOULD BE AWARE.OF THEM. THEY ARE:.. 1) TABLE OVERFLOW - AN INT ERNAL TABLE. HAS EXCEEDED ITS LIMITS. .. [CROSS.REFERENCE WILL NOT BE ABLE.T O INDEX A PROGRAM THAT DISPLAYS THIS.ERR OR.].. 2) PRINTER NOT READY - THE PRINTE R IS. NOT CONNECTED/TURNED ON......TH E TABLE OVERFLOW ERROR CAN BE.FLAGGED BY ANY OF THE FOLLOWING.CONDITIONS:.. 1) M ORE THAN 256 DIFFERENT. VARIABLES... 2) MORE THAN 256 DIFFERENT LINE. REFE RENCES... 3) THE LENGTH OF ALL VARIABLE NAMES. COMBINED EXCEEDS 768 BYTES... THIS UTILITY WILL PROVIDE YOU.WITH IN VALUABLE INFORMATION ON YOUR.OWN PROGRAM S, AND WILL HELP YOU.UNDERSTAND PROGRAMS WRITTEN BY OTHERS.AS WELL... NEEDLES S TO SAY, CROSS REFERENCE.HAS BEEN COPIE D TO MY UTILITY DISK..THOUGH RICK CLAIMS THAT HIS CODE WAS.WRITTEN LONG AGO AND THE SOURCE CODE.IS NOT AS LEGIBLE AS HE' D LIKE IT,.THE END PRODUCT IS FAST AND.E FFICIENT. ANY PROGRAMMER WOULD BE.HARDP RESSED TO PASS UP RICK'S UTILITY.AS THE MOST HANDY CROSS REFERENCER TO.DATE... A NOTE ABOUT USING CROSS.REFERENCE: TH E DEMO PROGRAM THAT.BOOTS CROSS REFERENC E IS NOT PART OF.CROSS REFERENCE AND WIL L NOT BE.COPIED BY LOADSTAR'S COPIER.
