I have an emulator and disk images, but I don't know the commands to
get a directory and load and run a program.  Can someone please help?
Thanks!

Hi Brian,

For starters, the floppy disk drives are called 0 and 1
(rather than A and B like in MS-DOS or MS-Windows).

(a) To get a directory listing of disk 0

    DIR 0

(b) To get a directory listing of disk 1

    DIR 1

(c) To run a BASIC program "XXXX.BAS" in drive 0

    RUN "0:XXXX.BAS"

    Don't forget the quote marks around the file.

(d) To load a BASIC program "YYYY.BAS" in drive 1,
    without running it at the same time

    LOAD "1:YYYY.BAS"

(e) To run a machine language program "ZZZZ.BIN" on drive 2
    (if you use 3 floppy disk drives, the third one is drive 2)

    LOADM "2:ZZZZ.BIN" : EXEC

Cheers,
Ralph.

The complete filespec is FILENAME/EXT:D for the various Tandy DOSes,
including Color Disk BASIC, where D is the drivespec (0 through 3
can be installed.)

The CoCo will accept _ANY_ of the following file specifications...

    "0:FILE.EXT"            -- similar to MS-DOS
    "0:FILE/EXT"
    "FILE.EXT:0"
    "FILE/EXT:0"            -- like Z80-based TRS-DOS

> >     RUN "0:XXXX.BAS"

_BOTH_ will work on the CoCo.

It makes sense when you remember that CoCo Disk BASIC was written
by Microsoft.  As a result, ...

1.  The disk system supports file specifications similar to MS-DOS,
    as well as the Z80-based TRS-DOS style.

2.  The CoCo disk format uses a FAT (File Allocation Table) more
    similar to MS-DOS than to the Z80-based TRS-DOSes.

Cheers,
Ralph.
