Command linearg puzzle - more

The 'funny' acting program a colleague showed me (see me earlier post) has provided a clue. Wen the debugger is used to examine the program, all is well. When the program executes via fglgo, bingo. I will propose that she has an uninitialized variable in her program somewhere, perhaps being used as a subscript, which is clobbering some other code fragment, resulting in the observed behaviour. Thanks to all for the help. From here on in, it'll be variable accounting. ---------------------------- My *real* .sig awaits future display technology (sent with Agent .99d/32)
