19 - Appendix B - FLEX UCS Summary

Note: The FLEX filesystem uses what is called an 8.3 naming scheme for filenames; that means that filenames can be up to eight characters long, with up to a three character extension.

Assumptions are common. For instance, anything that ends with .CMD can be typed without the extension at the command prompt, and FLEX will attempt to execute it. Files that end in .TXT are usually accepted by commands that deal with text files without you having to name the extension.

This kind of shortcut is common.

Here are some very minimal docs for the FLEX commands:

<> = REQUIRED    [] = OPTIONAL

H = HEXADECIMAL NUMBER DIGIT
D = DECIMAL NUMBER DIGIT
T = ASCII TEXTFILESPEC = [drivenumber][extension]

examples:  0.COPY.CMD
           COPY
           COPY.CMD
           0.COPY

DRIVESPEC = [DRIVENUMBER]
examples:   0
            1
            2

MATCHLIST = [PARTIAL FILENAME][EXTENSION]
examples:   C
            C.CMD
            CO
            CO.CMD
            COPY.CMD

DRIVELIST =  [DRIVENUMBER] [DRIVENUMBER]...
examples:   0
            0 2
            0 1 3
            0 1 2 3
