A volume specifier in HTBasic is similar to an MSUS (Mass Storage Unit Specifier) in HP BASIC. However, for disk volumes with multiple directories, a volume specifier does not completely identify a place to store files (see Path Specifier).
Two types of volume specifiers are supported by HTBasic. The first is the drive letter such as, "C:". If used with a file specifier, it is appended onto the front of the filename, "C:DATA".
The second type of volume specifier supported by HTBasic is the HP BASIC compatible msus style. For example, ":CS80,700,0". Support for this type is included for compatibility with old HP programs. To use this type of volume specifier you must use CONFIGURE MSI to define a connectioin between this type of volume specifier and the HTBasic Windows system. For example:
