Display the contents of a minor frame file.
Displays the contents of a minor frame file. The contents are printed to the terminal, the line printer, or a disk file. The minor frame file is a label services file containing the HRPT minor frame data associated with an AVHRR LAS image.
- IN
- Input image. The name of the AVHRR LAS image for which the associated minor frame file will be displayed. The file extension for the minor frame file is assumed to be ;MNR.
- SL(1)
- Starting line. The line number at which reporting will begin. See User Note 2.
- NL(--)
- Number of lines. Number of lines of minor frame data to display. If the end of the minor frame file is encountered before NL lines of data have been displayed, processing will terminate. By default, the remainder of the file starting at SL will be displayed.
- LISTOPT("ON","ON","ON","ON","ON","ON","ON")
- List options. Display of the following fields in the minor frame file may be turned "ON" or "OFF" in the resulting report:
Frame Sync Data ID Data Time Code Data Telemetry Data Internal Target Data Space-Scan Data Sync Delta Data
- PRINT(TERM)
- Output destination. The destination of the output.
= TERM: Terminal. Output is sent to the user's terminal. = LP: Line printer. Output is sent to the printer defined by $PRINTER. = Filename: User-supplied filename. Output is sent to the user-supplied file with the extension ";PRT".
Minor frame data starting at line 500 from the minor frame file AFRICA;MNR are read, formatted, and displayed to the user's terminal. Processing will continue until all remaining lines in the file have been displayed. All fields in each line are reported.
Lines from the minor frame file SAMERICA;MNR are read, formatted, and output to the printer. Data from lines 200 through 209 will be displayed. Only internal target data will be displayed for each line.
The appropriate lines from the minor frame file are read, formatted into a report, and routed to the specified output destination.
The error message displayed immediately preceding this message is the specific error encountered. Processing is terminated.
The specified number of lines to display is less than one. Check the values of SL and NL.
The temporary file used to route the output to the specified destination cannot be opened. Verify write permissions in the current directory.
If NL is not specified, NL will be determined by reading the image's associated Data Descriptor Record (DDR). The associated DDR is expected to have the same root file name as the minor frame file and a suffix of ;DDR. Make one of the two sources for NL available.
An error occurred reading the minor frame file. The file has been corrupted. Regenerate the minor frame file using AVHRRIN.
