DMP or DUMP is used to dump files in various readable formats. It has two basic modes of operation: FILE MODE and DEVICE MODE. In FILE MODE, the device must be mounted for access by FCS. To dump logical blocks or records of a file use FILE MODE. In DEVICE MODE, the device must be mounted FOREIGN on 11M+. To dump physical blocks from a device, use DEVICE MODE. The general form of the command line is: outspec/switches = inspec/switches where: outspec is the output file specification for the dump. (TI: is acceptable.) inspec is the name of the file to be dumped (FILE MODE only) or the input device specification in DEVICE MODE. Legal switches are: /AS Dump in ASCII mode /BA:n:m Specifies two word base address /BL:n:m Specify logical block range to dump in FILE MODE,default is entire file. or Required switch in DEVICE MODE, specifies range of physical blocks to be dumped. /BY Dump in byte octal format /DC Dump in decimal format /DENS:n Density for input magnetic tape /FI:filenum:seqnum Identify input file by File ID The following three switches may be combined with the /BL switch to specify a range of blocks to be dumped. For instance, /HD or /HD:U followed by /BL:0 will dump only the header of the file. If followed by /BL:n:m, logical block n thru m of the file will be dumped along with the header of the file. /HF/BL:n:m will dump the logical blocks of the file from n thru m in header format, if they conform to ODS-1, otherwise they will be dumped in octal. /HD Dump file header in formatted form /HD:U Dump file header unformatted /HF Dump in ODS-1 header format /HX Dump in hexadecimal format /ID Display current version of DMP program /LB Display starting LBN of file /LC Dump lower case characters as such /LIM:n:m dump only n thru m bytes /LW Dump in hexadecimal double word format /MD:n Specify line number sequencing /OCT Dump in octal format. /RC Dump in record (instead of block) format /RW Rewind the magtape before dumping /R5 Dump in RAD50 format /SB:n Space n blocks in indicated direction. Tape only in device mode. /SF:n Space n EOF's in indicated direction. Tape only in device mode. /SP Spool output file to line printer /WD Dump in hexadecimal word format NOTE: A command line line may specify one or more of DMP's format switches in the same command line. However, some of them are mutually exclusive (see the documentation for more detail). If no switches are specified, /OCT is the default.
