The traces look OK with "p1", which I assume means that they are "in memory".

According to the SAC book, I can do: systemcommand to list cat list_file while read list filename read filename enddo However, I get the error: "sh: to: command not found" Why isn't this working? According to the online command index there's no "to" syntax for systemcommand: http://ds.iris.edu/files/sac-manual/commands/systemcommand.html Is there a different way to do this? Thanks, Sh… [more]
