Command: RUN VCRIDX


FUNCTION:

     Calculate, print and display the number of blocks per PPN from a
     VCRDIR file.  Output to xxxxxx.LST and terminal.

HINTS/RESTRICTIONS:

     The current version requires 135K bytes of user memory.
     Max block count per PPN = 65,535.
     The program scans the directory file for a device name (eg. DSK0
     or WIN4).  Only one device may be scanned per program run.

FORMAT:

     .RUN VCRIDX [ret]

OPERATION:

     First, create a VCR directory file using the AMOS VCRDIR program.
     A sample use is ".VCRDIR AMUS87.VCR=ALL:[]".  (Note the use of .VCR
     as the extension for the vcr directory file.)

     Next, run VCRIDX to scan the directory and produce a summary
     matrix of block counts by PPN.

     At the AMOS . prompt type RUN VCRIDX and press [ret].

     The screen will be cleared and the following prompts will appear:

          File Name: _
          Extension: VCR
          Summarize device from vcr directory(eg, DSK0):

     Enter the file name of a file created by the VCRDIR command.

     At "File Name: " Enter {optional device and PPN and} up to
     6 character file name.

     The file extension defaults to ".VCR".  This may be overwritten.

     The device name to be entered is that device name to search for
     on each line of the VCR directory file.  The device "ALL" will
     cause the program to summarize all lines in the file.

     The program now reads the seven heading lines of the directory
     and displays them on the screen and writes them into the output
     ".LST" file.

     The following "heading" is displayed:

                                  Blocks
                Seq.  Prj PNo  /File  /PPN
               =====  === ===  ===== =====

     followed by a line for each line in the directory.  If the line
     matches the device then a status line is displayed below the 
     heading.  If the line does not match then the word "SKIP" is
     displayed. 

     After reading the directory file, a matrix of block counts by PPN
     is displayed and written to the .LST file.
