I know; this is an ASCII window on my MacBook so you = won't be able to show the code :-) The goto operator is "-> label", while assignment is "var <- value" In Ken Iverson's 1962 book "A Programming language" he shows branches by showing flowchart like arrow connecting a source stmt to target but he doesn't use any goto or branch operator symbol or labels. So not sure what John means. As a grad student I did part time programming for a prof doing research in cancer epidemiology. I convinced him to let me use APL instead of PL/I but the "funny money" quickly ran out and it was back to PL/I!=
