System files

EDT makes it possible to read from SYSDTA and write to SYSOUT and SYSLST.

The handling of character sets when accessing system files is described in section “Character sets”. The system files SYSLST and SYSOUT should only be assigned to files or library elements with a Unicode character set if it is certain that only EDT sends output to these files. Otherwise files containing invalid characters could be created since other system components do not usually take account of the character set assigned to SYSLST or SYSOUT.
