MASS STORAGE IS (MSI/CD)

MASS STORAGE IS, and its abbreviated aliases MSI and CD, allow you to specify the device and path specifier to be used by default when no explicit device and path specifier are given. For example, a CAT command without a path specifier will display files from the default path specifier. As another example, these two programs ASSIGN the same two files:

MSI "D:"

ASSIGN @File1 TO "FILE1"

MSI "E:"

ASSIGN @File2 TO "FILE2"

ASSIGN @File1 TO "D:FILE1"

ASSIGN @File2 TO "E:FILE2"
