The symbolic name of the tape drive from which the data is to be read. Must be the same name used in the TAE MOUNT command. Example: TAE>ALLOC MTA0 TAPE TAE>MOUNT TAPE TAE>CONVIM TAPE A
The names of the VICAR2 files to which the tape data sets are to be written. There must be at least as many output file names given as input data sets to be read. Any additional file names will be ignored. Example: FILES=(4,5,6) OUT=(RED,GREEN,BLUE) would copy file number 4 to RED, file number 5 to GREEN, and file number 6 to BLUE.
Each number indicates the files to be read from the tape. For example, FILES=(4,6,8) would read the fourth, sixth, and eighth files from the input tape. There must be a corresponding number of outputs.
A window into the input file which is to be written to the output
file. WINDOW is in the standard size field format,
WINDOW=(SL,SS,NL,NS) where
SL is the starting line to read for output
SS is the starting sample to read for output
NL is the number of lines to be written
NS is the number of samples to be written.
To default a field in WINDOW, it may be left out or set to 0.
For example, WINDOW=(5,1,0,10) would default the number of lines
in the window to the true number of lines in the image.
WINDOW=(5,5) would default both NL and NS.
The defaults are
SL -- 1
SS -- 1
NL -- Total NL in input
NS -- NS from the label if labeled input, logical record
length if unlabeled. See defaults for RECLEN.
Number of lines to be used unconditionally for every image read from the tape. If the actual number of lines is less than NL, only the actual number will be read. If the actual number is larger than NL, then only NL lines will be read. NL's primary purpose is to provide an image size for unlabeled images. It provides information about the input image only, and does not provide a window into the input.
The number of bytes (NOT samples!) per line to be used unconditionally
as the logical record length of each input file. RECLEN is used to
unblock blocked tapes, not to determine the image size.
The defaults for RECLEN are as follows:
For a labeled input: NS from the label
For an unlabeled input: The physical block size on the tape
If the logical record length of the tape is different from the
line length of the input image, RECLEN MUST be given in order for
the data to come out correct.
FORMAT is used to specify a pixel format to be used unconditionally for every image to be read. The valid values are: BYTE 1 byte unsigned integer HALF 2 byte signed integer FULL 4 byte signed integer REAL 4 byte floating point REAL8 8 byte floating point (Not yet available) COMPLEX 2 4 byte floating points For labeled inputs, the default format is taken from the label. For unlabeled inputs, the default format is BYTE.
The keyword LABEL is used to force all input files to have image labels on output, whether or not they had one on input. For unblocked images, if NL, RECLEN, or FORMAT are not specified, the system information is taken from the block format of the tape, assuming one record per block.
