R

The PROMPT environment variable is not used by MiniCMD.  The MiniCMD

prompt is a single >" character.  If a PROMPT environment variable is defined,

it is passed to all programs and child processes, along with all the other defined

environment variables.
Although environment variables can be defined, they cannot be used within

ROMINIT.BAT in the same way that COMMAND.COM can use environment

variables.  The percent character (%) is not treated as a special escape character

used to substitute the value of an environment variable into a command.
Other than the internal commands defined in the preceding list, MiniCMD

strictly attempts to load and execute whatever you type, using a simple DOS exec

command.  Thus, to execute a program, you must specify the full path name for

the program on the command line.

type

A:\DOS\CHKDSK.EXE

or

A:CHKDSK.EXE

or

CHKDSK.EXE

but not

CHKDSK

Note that file extensions receive no special treatment.  You can rename

executables to have any extension, or even no extension, and still execute them.
ROMINIT.BAT, loaded when DOS first boots, is the only batch file executed by

MiniCMD.  Furthermore, the only batch file you can invoke from the MiniCMD

prompt is ROMINIT.BAT.  You can reinvoke ROMINIT.BAT only by typing the

file name for MiniCMD, which, in turn, restarts MiniCMD.
Every time MiniCMD is executed, it looks for and executes ROMINIT.BAT.  You

do lock up if you attempt to execute another batch file by name, either in

ROMINIT.BAT or at the MiniCMD prompt, because MiniCMD attempts to

execute that batch file as if it were a binary program.

R

All the messages displayed by MiniCMD have been shortened or split into

multiple lines so that they fit the 20Ćcolumn screen on the 6200 Computer.

"

The @ command prefix is added.

"

Prompt character is changed to the familiar > character.

"

The critical error handler in MiniCMD now displays a menu that includes

numeric responses so that you can respond without using an alpha

keyboard.  For example, Abort, Retry, Fail?" becomes

2) Abort,

1) Retry,

3) Fail?

The numbers are not always in order so each line is displayed independentĆ

ly, depending on the available options.  If the numbers were altered to apĆ

pear correct for one condition, they would appear wrong for another.

"

Echo command is modified to allow ECHO," to display a blank line instead

of Cannot load program."  Also, comma (,), equals (=), and quote ()

terminate a keyword comparison.

"

A GOTO bug is removed to work with labels of two or more characters.

The diskĆbased version of MiniCMD is used to favor the executeĆinĆplace

ROMĆbased version.  Also, the diskĆbased version is modified so that there

was no back door for exiting MiniCMD.  The diskĆbased version was

originally intended to test MiniCMD, and the back door for exiting it was

used to get back to a normal COMMAND.COM.
