The memory layout for the Interdata simulators has been changed. Do not use Interdata SAVE files from prior revisions with V3.4. 1. New Features in 3.4 1.1 SCP and Libraries - Revised interpretation of fprint_sym, fparse_sym returns - Revised syntax for SET DEBUG - DO command nesting allowed to ten levels 1.2 Interdata - Revised memory model to be 16b instead of 8b 1.3 HP2100 - Added Fast FORTRAN Processor instructions - Added SET OFFLINE/ONLINE and SET UNLOAD/LOAD commands to tapes and disks 2. Bugs Fixed in 3.4-0 2.1 Interdata - Fixed bug in show history routine (from Mark Hittinger) - Fixed bug in initial memory allocation 2.2 PDP-10 - Fixed TU bug, ERASE and WREOF should not clear done (reported by Rich Alderson) - Fixed TU error reporting 2.3 PDP-11 - Fixed TU error reporting
