help

hi

 I am facing a strange problem while running the code in
/gprolog-1.2.16/ExamplesC.

 I issue the make command and then run the file new_main. It ask
 for input and i give john as the answer. But it doesn't return the
answer as shown in the manual.

 It gives the following error message.
Fatal Error: Pl_Query_End(PL_RECOVER) but unrecoverable query

 However when i change the flag for Pl_Query_End from PL_RECOVER to
 PL_KEEP_FOR_PROLOG it just gives me only one or no solutions. THe other
 solutions though exist will not be displayed.

 Somebody please help.

regards
vibhav
