The time values can be expressed in terms of milliseconds by using the flag *u=msec. Seconds are indicated by using the flag *u=sec as demonstrated in the following example.

cat file.krn | programis equivalent to a web file using ths form:
echo http://www.some-computer.com/some-directory/file.krn | program
Besides the http:// protocol, there is another special resource indicator prefix called humdrum:// which downloads data from the kernscores website. For example, using the URI humdrum://brandenburg/bwv1046a.krn:
program humdrum://brandenburg/bwv1046a.krnwill download the URL:
Musedata Bach Brandenburg Concerto collection.
This online-access of Humdrum data can also interface with the classical Humdrum Toolkit commands by using humcat to download the data from the kernscores website. For example, try the command pipeline:
humcat humdrum://brandenburg/bwv1046a.krn | census -k
