NEWDOS/80 v2.0 Reference (One Page)

The following is republished on my site, unchanged (other than this line and a needed update to HTML5/CSS), with permission of Pete Cervasio and of Sander Berents.

This is a copy of the NEWDOS/80 Version 2 REFERENCE CARD. This card is a short reference guide for the manual provided by Apparat with NEWDOS/80 Version 2 released in August 1981.

LaTeX version by Sander Berents (Januari 1996)

General statements for DOS commands:

• The user should refer to chapter 2 of the manual for more detail as needed;
• If your NEWDOS/80 does not use passwords then the parameter is not needed in file specifications and the parameter is not needed in PDRIVE, PROT, PURGE or SYSTEM;
• Commas may be replaced by spaces, except where two consecutive commas are used to indicate a null parameter between them;
• The word TO is always optional;
• Commands may be in either lower or upper case or a combination thereof. Lower case usage in non-DOS commands is dependent upon the function involved.

Append the contents of file1 to the end of file2.

APPEND,NEW/DAT:0,TO,OLD/DAT:1
APPEND NEW/DAT:0 OLD/DAT:1

Change the specified attributes (at least one required) of file1.
The following defines the valid values for options:

• INV - DIR will not display the file unless parameter I is specified
• VIS - DIR will display the file
• PROT=xxx - Assign file protection level xxx, where xxx can be one of
  • LOCK - No access
  • EXEC - Execute
  • READ - Execute or read
  • WRITE - Execute, read or write
  • RENAME or NAME - Execute, read, write or rename
  • KILL - Execute, read, write, rename or kill
  • FULL - All operations
• ACC=fpwd1 - fpwd1 becomes the file's access password
• UPD=fpwd2 - fpwd2 becomes the file's update password
• ASE=y or n - Enable automatic allocation of additional file space
• ASC=y or n - Enable automatic de-allocation of excess file space
• UPD=y or n - Turn on/off the file's updated flag.

ATTRIB CNTRLDAT/CMD,UPD=KKKJJJ,PROT=READ

The DOS command doscmd is stored in the system diskette's directory for automatic execution at subsequent re-boots. AUTO alone eliminates this automatic re-boot action.

AUTO,BASIC,RUN"MYPROG/BAS:0"

(Model I only) Enter Level II non-disk BASIC (no DOS, no disk BASIC).

BASIC2

Enable/disable cursor blinking.

BLINK,N

RE-boot the DOS system.

BOOT

Enable/disable the BREAK key.

BREAK,N

Enter keyboard input chaining mode, starting at the beginning of file1 if sectionid is not specified or the beginning of the section sectionid of file1 if section was specified. JCL is assumed as the name extension if none was specified in file1.

CHAIN MYCMDS/DAT:1

Alter chaining state. Options are:

• N --- Chaining is temporarily suspended and the current DOS-CALL level, if any, is exited

Multiple file copy. Distinguished from full diskette copy by the CBF (Copy By File) parameter. One, some or all of the files, excluding BOOT/SYS and DIR/SYS, of the source diskette are copied to the destination diskette. All excluded files and all non-allocated granules are not copied. If a NEWDOS/80 system disk is being created, FMT must be specified. All of the above options except BDU, are useable by this copy. If a system file is to be copied and it is not already in the destination diskette, FMT should be specified. Additional options are:

• ODPW=dpwd2 --- The destination diskette's old password must be dpwd2 or the format/copy will not be done
• DDSL=ln1 --- Formatting will start the directory at the beginning of lump ln1
• DDGA=gc1 --- Format will allocate gc1 granules to the directory.
