What is the best procedure to install a newer version of XBASIC?
Rename \xb to \xbold (/xbasic to /xbasicold) before installing a new release of XBasic is best. That way if you modified any of the sample programs or anything else (like /xb/xxx/property.xxx) you can put any changes you want to keep into the files in the new release. But make sure you install per the directions – you should not create a new \xb directory manually, you should extract into the \ root directory with “recreate subdirectories” selected, which automatically creates all XBasic directories properly, including “/xb” “/xb/app” “/xb/xxx” and any others required by XBasic.
