    NAME

        List

    FORMAT

        List [(dir | pattern | filename)] [ PAT (pattern)] [KEYS] [DATES]
             [NODATES] [TO (name)] [SUB (string)] [SINCE (date)] [UPTO (date)]
             [QUICK] [BLOCK] [NOHEAD] [FILES] [DIRS] [LFORMAT (string)] [ALL]
                
    TEMPLATE

        DIR/M,P=PAT/K,KEYS/S,DATES/S,NODATES/S,TO/K,SUB/K,SINCE/K,UPTO/K,QUICK/S,BLOCK/S,NOHEAD/S,FILES/S,DIRS/S,LFORMAT/K,ALL/S

    LOCATION

        C:
           
    FUNCTION

        Lists detailed information about the files and directories in the 
        current directory or in the directory specified by DIR.

        The information for each file or directory is presented on a separate 
        line, containing the following information:
         
        name
        size (in bytes)
        protection bits
        date and time
        
    INPUTS

        DIR           --  The directory to list. If left out, the current
                          directory will be listed.
        PAT           --  Display only files matching 'string'
        KEYS          --  Display the block number of each file or directory
        DATES         --  Display the creation date of files and directories
        NODATES       --  Don't display dates
        TO (name)     --  Write the listing to a file instead of stdout
        SUB (string)  --  Display only files, a substring of which matches
                          the substring 'string'
        SINCE (date)  --  Display only files newer than 'date'
        UPTO (date)   --  Display only files older than 'date'
        QUICK         --  Display only the names of files
        BLOCK         --  File sizes are in blocks of 512 bytes
        NOHEAD        --  Don't print any header information
        FILES         --  Display files only
        DIRS          --  Display directories only
        LFORMAT       --  Specify the list output in printf-style
        ALL           --  List the contents of directories recursively

        The following attributes of the LFORMAT strings are available

        %A  --  file attributes
        %B  --  size of file in blocks rather than bytes
        %C  --  file comment
        %D  --  creation date
        %E  --  file extension
        %F  --  volume name
        %K  --  file key block number
        %L  --  size of file in bytes
        %M  --  file name without extension
        %N  --  file name
        %P  --  file path
        %S  --  superceded by %N and %P; obsolete
        %T  --  creation time
        
    RESULT

        Standard DOS return codes.
