The small cobol program below compiles and runs on our test MPE/iX 5.5 pp6 machine but on our production machine with same MPE/iX 5.5 pp6, I get a compiler error: INTRINSIC clock NOT FOUND IN INTRINSIC FILE. Does anyone know why this would happen? $control post85 identification division. program-id. test. environment division. configuration section. data division. working-storage section. 01 time-disp pic x(7). 01 time-comp pic s9(9) binary sync. procedure division. main. call intrinsic "clock" giving time-comp move time-comp to time-disp display time-disp stop run. -- Brad Feazell
