File processing

EDT can be used to process ISAM files, SAM files, library elements and POSIX files. These files are loaded into work files for processing. When the term “file” is used below, it is intended to refer to all four of these file types.

EDT also provides input/output interfaces to the BS2000 system files SYSDTA, SYSOUT and SYSLST.

The handling of character sets on read and write operations is described in section “Character sets”. Files with character sets which are not known in XHCS cannot be processed.
