# Debugging Aid

When D$ is longer than 704 characters, report 5 errors prevent you from displaying the array when you PRINT D$. This short routine appended to PRO/FILE lets you read all the contents of D$ without a lot of fuss. Begin numbering the lines at 9000 or some other place where there’s room.

```
9000 LET Y=704
9001 LET X=Y-703
9002 PRINT D$(X TO Y)
9003 LET K$=INKEY$
9004 PAUSE 32000
9005 IF K$="" THEN LET Y=Y+704
9007 CLS
9008 IF D$(X)=" " THEN GOTO 9010
9009 GO TO 9001
9010 STOP
```
