Howard. The new versions do not depend on an external large number library, offer GNU bc extensions, are much faster than and fix POSIX compliance issues of the programs they replace. They support POSIX message catalogs and come with localized messages in Chinese, Dutch, English, French, German, Japanese, Polish, Portugueze, and Russian. The previous implementation is still available in FreeBSD-13 and can be selected instead of the new one by the build option WITHOUT_GH_BC. c41fef90a7d I like to use bc and dc with some scripts to calculate things and used this script. I do not mind the changes, all I would like to see if it is possible to add something to script so it can stop like it used to before. Best Regards, Antonio
