1- Syntax/Options 2- Notes 3- Examples of Use
QUIET sets, resets, and displays the QUIET flag in the ZCPR3 Environment
Descriptor. It's best use is in reducing text output from crucial utility
programs such as CD, LDR, LX, PATH, REG, etc. Vs 1.0 (3/84) by R. Conn.
Many ZCPR3 utilities read the QUIET flag in the ZCPR3 Environment
Descriptor and respond accordingly. If the QUIET flag is set (ON), then
certain informative messages are suppressed in order to cut down on the
'noise' created by the command. If the QUIET flag is reset (OFF), then all
messages are displayed.

Syntax QUIET {{/}option}
If no option is given, DISPLAY is assumed. A slash before the option is
allowed, but not required.
Options
Only enough letters are required for the option to be unique. That is,
only a single letter is necessary for all options except ON and OFF, which
require two letters.
DISPLAY Displays current state of quiet flag. This is the
default option.
SET Turns on (sets) quiet flag.
RESET Turns off (resets) quiet flag.
ON Turns on (sets) quiet flag.
OFF Turns off (resets) quiet flag.
If the wheel byte is off (reset), the SET/RESET and ON/OFF options cause no
display on the console. If an invalid option is given, the program error code
is set to 19 and the error handler is invoked, if one is running.

QUIET Notes
a. Version 1.2 updates (Gene Pizzetta, 06/24/90):
- It seems a little silly for QUIET to obey the quiet flag, since the
flag is apt to change while the program is running. Instead, this
version uses the wheel byte like a quiet flag.
- Also added ON and OFF as alternate options for SET and RESET.
- Made DISPLAY option the default.
- Now allows leading slash for options.
- Added Type 3 header.
- Displays version and load address only on the help screen.
- Sets program error flag and invokes error handler if invalid option is
given.
- Now uses library routines for most functions.
- Uses actual program name on help screen.
b. Version 1.1 updates
- Observance of quiet flag for display of help screen.
- Z80-specific opcodes.
- Printing of program name and version number with D option.
