Commands:
DATA Specifiy the name of the data file to be used as in
a normal command string "DATA=DEV:FILE.EXT[P,PN]".
MAKE Call TABLE.SAV to create the conversion tables.
EXIT Terminate the program.
HELP This little message.
BYE Call LOGOUT into core and execute it.
RETAIN Allows the user to accumulate commands.
RUN Perform the current command string.
ERASE Erase retained commands.
PRINT Print the current command string.
Switches:
Buffers:x Use x buffers.
Advance:x Advance x files before operation.
Backspace:x Backspace the tape x files before operation.
Block:x Set blocking factor to x.
Record:x Set record size or size of largest block to x.
Density:arg Set mag-tape density to arg [arg=200,556,800].
Retain Retain the following commands.
Run Perform the current command and retain it.
Help These few hints.
Label:arg Set label type as described below for mag-tape
ode:arg Set file character set as described below.
Parity:arg Set mag-tape parity [odd=odd, even=even, default=odd].
Password:arg Set the password for GE labels.
Reel:x Set serial number in labels that have this feature.
* Industry Initialize for industry compatible 9-channel tape.
* Scan Scan tape for file named.
* Error Don't ignore checksum and parity errors.
* Span Records cross blocks [implied if "/block:0"].
* Rewind:arg Rewind tapes [arg=before, after, always, omitt]
* Unload Unload tape after operation.
* Tell Type file names on a wild card search.
* List List the device directory.
* Flist List the device directory [file names only].
* Header Print headers on the line printer.
* Crlf Ascii file has crlf's.
Note: To turn a switch off concatenate "no" with the switch.
Switches flaged with an (*) have this feature.
/Label - switch modifiers:
None Mag-tape has no labels just data [default].
Mine Special labels for DECsystem-10.
Digital Process labels as standard DIGITAL labels.
Burroughs Process labels as standard BURROUGHS labels.
IBM Process labels as standard IBM labels.
GE635 Process labels as standard GE-635 labels.
Note: Labels are written in the mode specified except for IBM
and GE-635 labels. IBM labels are written in BCD for
7-track drives and EBCDIC for 9-track drives. GE-635
labels are always written in GE-BCD.
/Mode - switch modifiers:
ASCII File character set is 7-bit ASCII.
HPASCII File character set is 8-bit ASCII.
GEASCII File character set is 9-bit ASCII.
IMAGE File is read and written as 36-bit words.
SIXBIT File character set is SIXBIT.
FIXSIX File character set is SIXBIT with no control words.
BCL File character set is BCL.
BCD File character set is BCD.
GEBCD File character set is GE-BCD.
HONBCD File character set is HONEYWELL BCD.
EBCDIC File character set is fixed EBCDIC.
VEBCDIC File character set is variable EBCDIC.
The end of the input record is determined by the mode of the
input file as described below:
ASCII Terminated by a carriage-return character or record count.
SIXBIT Determinted by the header word in front of each record.
FIXSIX Always copies the number of bytes specified by the record size.
BCL Always copies the number of bytes specified by the record size.
BCD Always copies the number of bytes specified by the record size.
EBCDIC [Fixed] Always copies the number of bytes specified by the
record size.
EBCDIC [Variable] Determined by the header word in front of each
record.
In general all commands may be abbreviated to any number
of characters that will allow that command to be unique. However
no more then six characters are checked for valdit in any of
the commands.
The characterS "?" and "*" may be used to denote a wild card for files
on mag-tape, disk, or dectape. The character "@" denotes a
command file which CHANGE will read for commands. The "@" must
be at the END of the file name. If only
an altmode is typed change will enter dialog mode.
