filex.hlp
There are 8 other files named filex.hlp in the archive. Click here to see a list.
Commands are of the form:
dev:file.ext[p,pn]<prot>/s=dev:file.ext[p,pn]/s
The input (right-hand) side may have more files in the same format,
separated by commas.
dev: defaults to DSK:
file, .ext default to *
but .TMP files are not included in .* when reading from DSK:
prot defaults to system standard, <233> on PDP11 tapes
/s is a switch letter
(ssss) is ok for multiple switches
files are transferred in binary and individually at all times, except in
some cases of /V and /F
switches are:
/A forces ascii processing of /V and /F files
/B forces binary file transfers
/C says file is compressed (PDP10 .SAV)
/D says file is PDP6 .DMP format
/E says file is PDP10 .XPN format
/F says tape is a PDP fifteen tape
/G says go on in case of I/O errors
/H says help message (no file transfers are done)
/I forces image mode on /V tapes
/L says list file directory of tape (do not say TTY:; that's assumed)
/M says tape is project MAC format
/O says tape is old PDP6 format
/P says same as /Q but preserve the temp file
/Q says quick mode processing (copy in big gulps between dsk and tape)
/R says same as /Q but re-use temp file (don't access tape)
/S says file is a project MAC save file (SBLK)
/T says tape is a normal PDP ten tape
/V says tape is a PDP-ele-V-en tape
/Z says zero the tape; "^tapeid" or "[p,pn]" may appear with /Z for
tapes where this is meaningful
In /P, /Q, or /R if two devices are given in the file spec, then the
second device defines the name of the temp file (which is given
extension .DTA).
In the event no switches direct processing, file extensions cause the
right thing to happen in the following cases:
.DMP implies /D
.SAV, .LOW, .SVE, .SHR, .HGH, .EXE imply /C
.XPN implies /E
These file extensions are implied for output files with those switches
too, as is .BIN for /S. When /C is explicit or implied, .SHR, .HGH, and
.EXE are assumed to be in their standard formats respectively.
When transferring from .EXE to .HGH or .SHR, the high segment extension
is determined from the contents of he input file. Also, a .LOW file
will be created if needed.
When transferring from .HGH or .SHR to .EXE, a .LOW file will also be
read if needed.
In the case of /V, the following extensions imply /B processing: .BIN,
.OBJ, .SYS, .LDA, .LDR, .LOD, .LBO, .MFD, .UFD, .SYM otherwise, /A is
assumed
In the case of /F, .ABS implies /B (not IOPS), and .BIN implies IOPS
binary transfers. Otherwise, IOPS ascii is assumed for output to /F,
and IOPS headers are checked for input from /F
