Examples
define procedure ( listing, {{ description, string }, {count, numeral}} )
{
echo( new line, description[], " (Containing ", count[], " entries)" );
table process( list, echo( [Date Created]," ",[Time Created]," ", [Path], [Name] ) );
}
// Both listings are equivalent.
path[] = system info[bin directory];
echo("Using following main path: ", path[] );
rv[] = directory listing( list, path[] );
listing( "All files in specified subdirectory", rv[]);
rv[] = directory listing( list, path[] + "\L*,B*" );
listing( "All directories and files brginning with L or B", rv[]);
echo;
rv[] = directory listing( list, path[], "*", directories );
listing( "All subdirectores. Note: Use '*', not '*.*'.", rv[]);
echo;
rv[] = directory listing( list, path[]+"\lib", "*.txt" );
