Controlling a persistent progress bar
Command line options of the ppbS program are used to control a ppb. Every manner of control over a ppb is managed through a verb and verb arguments. You can have any number of verbs in the command line.
DOS> ppbs crawl 1
N is the ppb window number.
Crawl should be used before a lengthy process starts. The ppb will continue to update while the lengthy process is running.
Crawl loops continuously from 0 to 100. You would probably not want to show the percent while doing this crawl.
The ppb increments one percent every 125 milliseconds (8 times a second). This rate can be changed using SetCrawlTime or SetCrawlSpeed.
