Detailed Description

describes one tape or trace header field,

Note: it is important to know whether your HdrEntry is in 'internal' or in 'user' format. The difference is 1 byte. For example, tracr is at byte 4 of the trace header, but users need to see 5. The reasone we don't always use internal entries is that some things have to be directly stored in user settings.
