Global variables and RDS

Hello all, Currently I am trying to work out why the RDS debugger core dumps on a program when the runner works fine. Both the runner and debugger have been recompiled to include some 'c' functions. I have a suspicion that the root of the problem is globals files, although I am not sure why. Our programs are constructed from sets of libraries cat-ed together with the 4gos for the program itself. The mechanism leads to several different globals 4gos being cat-ed into the one program. The globals files themselves contain some duplicated record definitions, however limited testing with small sample global files has not enabled me to duplicate the problem. The source 4gls are spread out through a number of different directories, with read permission, with only the current directory and directories containing the globals files being listed in DBSRC. The 4gi's that are created are not very large (< .5mb). Thanks for any suggestions Mark Denham BBC London, UK Mark.Denham@bbc.co.uk
