This account contains the software we at the Rockwell Graphic Systems Division in Lombard, Illinois have developed by modifying the standard DEC autoload overlay code. Please refer to the Fall 82 DECUS paper, AST's And SST's In An Overlay Environment, and the Fall 84 DECUS paper, The Well-Tempered Cluster Library for information regarding the motivation behind these files. The files in this account fall into five groups : 1) The RUNOFF file ASTPAPER.RNO, which is the text from the Fall 82 DECUS paper, AST's And SST's In An Overlay Environment. 2) The Autoload Overlay routines, which are to be placed in SYSLIB. 3) The macro files (extension .MCR), used by the Autoload routines and to be placed in RSXMAC.SML. 4) The AUT Autoload Overlay Trace Receiver Task. This task is written in "C". It must be compiled on your own system, because licensing arrangements prohibit our distributing task's using our vendor's run-time routines. 5) The ATF Autoload Overlay Trace Formatter Task. This task is also in "C" source form only. Miscellaneous object files from subroutines which we wrote are supplied for use with the AUT and ATF tasks.
