I have tried the following, and it seems to work in the following simple example: WebThe simplest form of the command is open (unit = number, file = " name ") . In place of number you insert a positive integer (but not 6) to be used to refer to the file, and instead of name you insert the name of the file. Here are examples of open commands: open (unit = 2, file = "scores") open (unit = 7, file = "a:scores.txt")
