This will work though

5 Folder$="games\mygear"
10 r$="Directory found"
20 on error r$="Not found": goto %50
40 CD Folder$
50 Print r$: on error

If you wish to confirm if a file exists I found the best method is using the dot command .filesize
.filesize myfile

This puts the file size in variable T.  If no file existing T=0
This command isn't in the distro you have to add it to the dot directory to use

Thank you. Someone tells me a way in NextBASIC (using ON ERROR) to check for existance of a file or directory.

Sorry no-one has got back to you on this. Here's how I'd do it in SE Basic IV.

10 EXISTS = 1
20 FOLDER$ = "FOLDER"
30 ON ERROR GOSUB 100
40 CHDIR FOLDER$
50 IF EXISTS = 1 THEN PRINT "Folder exists": ELSE PRINT "Folder does not exist"
60 END
100 ON ERROR STOP
110 EXISTS = 0
120 RETURN

I need it under NextBASIC, and there´s no BASIC built-in command for doing this query from NextBASIC yet.

Thank you!
