To make STOIC and RED work under version 4 of VMS: Insert at the end of module SAO$STOIC:IMAGE insert the statement: 'IMAGE : IMAGE_WRT ; Then do a STOBUILD. Everything should be OK. You have produced a writable images for STOIC and RED. This image, I believe, is not sharable, so if you want to install it with the INSTALL command, use the /OPEN and /HEAD switches only. The sharable image feature was to increase RED's efficiency on heavily loaded edit-intensive systems.
