DISASM is based on an old program submitted by L.H. GERHARDSTEIN in 1973. It was modified to work with RSX11M+ (V4.1). There are some enhancements and corrections mainly within module 'disasm.mac'. The structures of the task-header were brought up-to-date. DISASM now knows some more about the internal task structure, i.e. it recognizes system images and privileged task structures. This information will be printed by the 'TSGT' or 'PSGT' services. The DISASM output file will get the same name as the input file (including the extension), therefore you should not enter the extension '.tsk' (this would result in an output file with extension '.tsk' -- this should be fixed). Default output extension is '.lst'. Linking the task will result in some undefined references, which can be ignored. U.Schmeling CSA Da.-Weiterstadt Waldstraße 29
