I've learned from the a discussion years ago http://groups.google.de/groups?hl=de&lr=&ie=UTF-8&threadm=NAYERI.95Jun9115820%40bermuda.gte.com&rnum=3&prev=/groups%3Fq%3Dcallback%2Bexception%2Bgroup:comp.lang.modula3%26hl%3Dde%26lr%3D%26ie%3DUTF-8%26group%3Dcomp.lang.modula3%26selm%3DNAYERI.95Jun911582 that it is intended that the program is aborted unrecoverably if it runs out of memory. This is not acceptable for GUI driven programs - the program cannot simply quit if the user enters a zero too much for a size value ... What is the current implementation in pm3 and cm3 ?
