Preliminary report on GRUMP: a symbolic FORTRAN dump. [For CDC 6600]
Ed. Fourt · 1977
This is a first report on the program GRUMP, which provides symbolic dumps of FORTRAN programs--specifically, of programs compiled by the Control Data FTN compiler--and which is now in operation at the Lawrence Berkeley Laboratory. By a ''symbolic dump'' is meant a printout which is generated and used like a standard octal or hexidecimal dump, to inform the user of the state of his program at some specific moment, generally the moment at which execution aborted; but which, in contrast to the octal dump, refers to all variables by their FORTRAN names, and gives their values in terms of FORTRAN-style encodings, rather than simply as unlabeled machine word images. This report is not really a guide to the use of GRUMP. Rather, it is a report on what has been accomplished and a tentative self-evaluation of the accomplishment, together with many items of interest to the systems programer who may be interested in putting up GRUMP at his own installation.
