The format of CAT output varies according to operating system. This behavior is compatible with HP BASIC. The CAT statement supports the use of wildcards. Again, wildcard interpretation varies by operating system. See CAT and WILDCARDS in the Reference Manual for more information.

 

Under DOS, HTBasic does not allow wildcards to be turned off as HP BASIC allows. Under UNIX, WILDCARDS are ON by default and the escape character is "\". HP BASIC uses wildcards as a primary filter and the SELECT option as a secondary filter in choosing filenames to display. HTBasic is designed to be used with one or the other. Use wildcards or the SELECT option, but not both.
