!DOCUMENT
!BASIC
COMMAND: BASIC Microsoft GW-BASIC for Sanyo MBC 550/555 MS-DOS 2.11
TYPE: External DOS command. Requires Sanyo IBM video board or MissingLink
Plus SoftVIDEO option.
PURPOSE: Run the GW-BASIC interpreter. Optionally executes the program name
given as a parameter. Same as BASICA.
SYNTAX:
BASIC [drive][filename]
EXAMPLE:
BASICA TEST loads the GW-BASIC interpreter and executes TEST.BAS.
As a result of hardware differences in the disk controller, keyboard interface,
and serial interface between the Sanyo MBC 550/555 Series computer system and
the IBM PC/XT/AT computer systems, the BASIC.COM, BASIC.EXE, and BASICA.COM
files for GW-BASIC supplied for the MBC 550/555 are different versions than
those supplied with standard MS-DOS/PC-DOS. However, syntax and usage are the
same in either case.
!BASICA
COMMAND: BASICA Microsoft GW-BASIC for Sanyo MBC 550/555 MS-DOS 2.11
TYPE: External DOS command. Requires Sanyo IBM video board or MissingLink
Plus SoftVIDEO option.
PURPOSE: Run the GW-BASIC interpreter. Optionally executes the program name
given as a parameter. Same as BASIC.
SYNTAX:
BASICA [drive][filename]
EXAMPLE:
BASICA TEST loads the GW-BASIC interpreter and executes TEST.BAS.
As a result of hardware differences in the disk controller, keyboard interface,
and serial interface between the Sanyo MBC 550/555 Series computer system and
the IBM PC/XT/AT computer systems, the BASIC.COM, BASIC.EXE, and BASICA.COM
files for GW-BASIC supplied for the MBC 550/555 are different versions than
those supplied with standard MS-DOS/PC-DOS. However, syntax and usage are the
same in either case.
!BLANKCGA
COMMAND: BLANKCGA by Rich Winkel for MS-DOS 2.XX and 3.XX
TYPE: External DOS command. Requires Sanyo IBM video board option.
PURPOSE: Blank the video board display after approximately 5 minutes of
inactivity to prevent permanent damage to the phospher of the CRT.
SYNTAX:
BLANKCGA
EXAMPLE:
BLANKCGA installs the memory resident program BLANKCGA to blank
the video board display after approximately 5 minutes of
inactivity. Place this command in the AUTOEXEC.BAT file
to install BLANKCGA at the time the system is loaded.
The time delay of 5 minutes can be changed to a longer or shorter period of
time by using DEBUG to modify the byte value at locations xxxx:0131 and
xxxx:0160. The delay in seconds is 14 times the byte value. The standard
value is 15H for a delay of 14 x 21 = 294 seconds or 4 minutes 54 seconds.
Replacing 15H with 0BH would change the delay to 14 x 11 = 154 seconds or
2 minutes 34 seconds.
!BLANKSV
COMMAND: BLANKSV author unknown for Sanyo MBC 550/555 only
TYPE: External DOS command.
PURPOSE: Blank the standard Sanyo video display after a specified period of
inactivity to prevent permanent damage to the phospher of the CRT.
SYNTAX:
BLANKSV [n]
where n is an integer specifiying in seconds the duration of the period of
inactivity after which the display is blanked until another key is pressed.
EXAMPLE:
BLANKSV 300 installs the memory resident program BLANKSV to blank the
standard Sanyo video display after approximately 5 minutes
of inactivity. Place this command in the AUTOEXEC.BAT file
to install BLANKSV at the time the system is loaded.
!CLEAR
COMMAND: CLEAR by Robert F. Soltau for MS-DOS 2.XX and 3.XX
TYPE: External DOS command.
PURPOSE: Clear console display when the ANSI driver is not installed. The
video mode is reset to BW80, the display is cleared, and the cursor
positioned in the upper left corner of the display.
SYNTAX:
CLEAR
EXAMPLE:
CLEAR sets video mode to BW80 and clears the console display.
!CONFIG
COMMAND: CONFIG by Timothy Purves for MichTron DS-DOS Plus 2.11
TYPE: External DS-DOS command.
PURPOSE: Set DS-DOS Plus 2.11 system drive flags for 40 track or 80 track
drives.
SYNTAX:
CONFIG
EXAMPLE:
CONFIG displays menu on console display device for selecting drive
types.
The system drive flags must be set for DS-DOS Plus 2.11 with the CONFIG command
before the system can access a drive. The flags may be temporarily set or
saved to disk. DS-DOS Plus 2.11 can only load the system from a 40 track disk
in a 40 track drive or from an 80 track disk in an 80 track drive irrespective
of how the drive flags have been set on the system disk using the CONFIG
command. However, after the system is loaded, DS-DOS Plus 2.11 can read and
write to 40 track disks in 40 track drives and 40 and 80 track disks in 80
track drives.
!DISKCOPY
COMMAND: DISKCOPY MS-DOS 2.XX and 3.XX
TYPE: External DOS command.
PURPOSE: Copy a diskette.
SYNTAX:
DISKCOPY [drive1] [drive2] [/1][/M]
where /1 is the switch to copy one side only, and
/M is the manual override switch (DS-DOS Plus 2.11 only) to
make a 40 track disk in an 80 track drive.
The first drive [drive1] is the source drive (copy from). The second drive
[drive2] is the target drive (copy to).
EXAMPLE:
DISKCOPY A: B: copies the diskette in A to B.
As a result of the Sanyo MBC 550/555 Series computer system using a different
disk controller than the IBM PC/XT/AT computer systems, the DISKCOPY.COM file
supplied for the MBC 550/555 is a different version than that supplied with
standard MS-DOS/PC-DOS. However, syntax and usage are the same in either case.
!DSKCPYV
COMMAND: DSKCPYV MS-DOS 2.XX and 3.XX
TYPE: External DOS command.
PURPOSE: Copy a diskette with the 8088 CPU replaced by a NEC V20 CPU.
SYNTAX:
DSKCPYV [drive1] [drive2] [/1]
where /1 is the switch to copy one side only, and
/M is the manual override switch (DS-DOS Plus 2.11 only) to
make a 40 track disk in an 80 track drive.
The first drive [drive1] is the source drive (copy from). The second drive
[drive2] is the target drive (copy to).
EXAMPLE:
DSKCPYV A: B: copies the diskette in A to B.
As a result of the Sanyo MBC 550/555 Series computer system using a different
disk controller than the IBM PC/XT/AT computer systems, the DISKCOPY.COM file
supplied for the MBC 550/555 is a different version than that supplied with
standard MS-DOS/PC-DOS. However, syntax and usage are the same in either case.
When running the NEC V20 CPU it is necessary to modify the DISKCOPY.COM file by
replacing each occurance of D40AD40A in the file with F6ECF6EC. DEBUG or a
suitable disk editor can be used to make the modification. It is customary to
rename the modified file as DSKCPYV.COM. DSKCPYV.COM will work with either the
8088 or NEC V20 CPUs. Similar modification is required for the FORMAT.COM and
IO.SYS files as well as the boot sector on the MS-DOS 2.11VB system disk.
!FORMAT
COMMAND: FORMAT MS-DOS 2.XX and 3.XX
TYPE: External DOS command.
PURPOSE: Format a diskette.
SYNTAX:
With MS-DOS 2.11, the syntax is
FORMAT [drive][/S][/1][/8][/V][/B]
where /S is the switch to transfer the operating system to the diskette
after formatting it,
/1 formats the diskette as single sided (default is double sided),
/8 formats with eight sectors per track (default is nine),
/V requests the volume name to be entered, and
/B leaves space on the diskette for an operating system to be
installed with the SYS command.
The MS-DOS FORMAT program can make 160K, 180K, 320K, and 360K disk formats.
With DS-DOS Plus 2.11, the syntax is
FORMAT [drive][/S][/M]
where /S is the switch to transfer the operating system to the diskette
after formatting it, and
/M is the manual override switch to make 40 track disks in an 80
track drive.
The DS-DOS Plus 2.11 FORMAT program automatically displays a menu on the
console display device for selection of format type and prompts you for a
volume label. 160K, 180K, 200K, 320K, 360K, 400K, and 800K formats are
offered with DS-DOS Plus 2.11.
With A-OK DOSX 2.11, the syntax is
FORMAT [drive][/S]
where /S is the switch to transfer the operating system to the diskette
after formatting it.
The A-OK DOSX 2.11 FORMAT program automatically displays a menu on the
console display device for selection of format type and prompts you for a
volume label. 160K, 180K, 200K, 320K, 360K, 400K, 720K, and 800K formats are
offered with A-OK DOS3 2.11 and A-OK DOS4 2.11. The A-OK DOSX 2.11 formats
are not compatible with machines running under MS-DOS/PC-DOS 3.XX format due
to an incorrect byte offset 11H in the boot sector of A-OK DOSX 2.11
formatted disks. To read the A-OK DOSX 2.11 formatted disks under MS-DOS/
PC-DOS 3.XX, change the boot sector byte at offset 11H on the A-OK DOSX
formatted disk from 07H to 70H.
EXAMPLE:
FORMAT B: formats the diskette in drive B.
WARNINGS: The FORMAT command destroys all files on the diskette.
A-OK DOSX 2.11, DS-DOS Plus 2.11, and MS-DOS 2.11
formatted disks can be read by a machine running any of
the these DOS versions. However, any attempt to write
to an A-OK DOSX 2.11 formatted disk from a machine
running DS-DOS Plus 2.11, and any attempt to write to
a DS-DOS Plus 2.11 formatted disk from a machine running
A-OK DOS 2.11 will destroy the disk's file allocation
table (FAT) and files on the disk will be thereafter
corrupted and unsalvageable.
As a result of the Sanyo MBC 550/555 Series computer system using a different
disk controller than the IBM PC/XT/AT computer systems, the FORMAT.COM file
supplied for the MBC 550/555 is a different version than that supplied with
standard MS-DOS/PC-DOS. However, syntax and usage are the same in either case.
An enhanced version of the FORMAT program is supplied with MS-DOS 3.2X and
3.3X. See the standard MS-DOS/PC-DOS 3.XX index for more information.
!FORMATV
COMMAND: FORMATV MS-DOS 2.XX and 3.XX
TYPE: External DOS command.
PURPOSE: Format a diskette with the 8088 CPU replaced by a NEC V20 CPU.
SYNTAX:
With MS-DOS 2.11, the syntax is
FORMATV [drive][/S][/1][/8][/V][/B]
where /S is the switch to transfer the operating system to the diskette
after formatting it,
/1 formats the diskette as single sided (default is double sided),
/8 formats with eight sectors per track (default is nine),
/V requests the volume name to be entered, and
/B leaves space on the diskette for an operating system to be
installed with the SYS command.
The MS-DOS FORMATV program can make 160K, 180K, 320K, and 360K disk formats.
With DS-DOS Plus 2.11, the syntax is
FORMATV [drive][/S][/M]
where /S is the switch to transfer the operating system to the diskette
after formatting it, and
/M is the manual override switch to make 40 track disks in an 80
track drive.
The DS-DOS Plus 2.11 FORMATV program automatically displays a menu on the
console display device for selection of format type and prompts you for a
volume label. 160K, 180K, 200K, 320K, 360K, 400K, and 800K formats are
offered with DS-DOS Plus 2.11.
With A-OK DOSX 2.11, the syntax is
FORMATV [drive][/S]
where /S is the switch to transfer the operating system to the diskette
after formatting it.
The A-OK DOSX 2.11 FORMATV program automatically displays a menu on the
console display device for selection of format type and prompts you for a
volume label. 160K, 180K, 200K, 320K, 360K, 400K, 720K, and 800K formats are
offered with A-OK DOS3 2.11 and A-OK DOS4 2.11. The A-OK DOSX 2.11 formats
are not compatible with machines running under MS-DOS/PC-DOS 3.XX format due
to an incorrect byte offset 11H in the boot sector of A-OK DOSX 2.11
formatted disks. To read the A-OK DOSX 2.11 formatted disks under MS-DOS/
PC-DOS 3.XX, change the boot sector byte at offset 11H on the A-OK DOSX
formatted disk from 07H to 70H.
EXAMPLE:
FORMATV B: formats the diskette in drive B.
WARNINGS: The FORMAT command destroys all files on the diskette.
A-OK DOSX 2.11, DS-DOS Plus 2.11, and MS-DOS 2.11
formatted disks can be read by a machine running any of
the these DOS versions. However, any attempt to write
to an A-OK DOSX 2.11 formatted disk from a machine
running DS-DOS Plus 2.11, and any attempt to write to
a DS-DOS Plus 2.11 formatted disk from a machine running
A-OK DOS 2.11 will destroy the disk's file allocation
table (FAT
