DlisBrowser shows the logical records in a convenient form as an hierarchical tree. Each record is shown as a branch which contains other branches, e.g. Reel Header Logical Record (RHLR) contains multiple Tape Header Logical Records (THLR), each THLR contains multiple File Header Logical Record (FHLR), each FHLR may contain Information Records (type 34), Data Format Specification Record (type 64), Data (type 0) and other records comprising FHLR. The content of each record is shown in another window in form specific for this record. If a record may contain data in various representation codes, for designating them data are printed in different colors.
