大家好，最近學了fortran程式，還不是很熟，這邊有個小問題要請教大家，問題如下
Write a Fortran that will read an arbitrary number of non-negative real
values and find the maximum and minimum of the input data.
To test your program, input the following data from a data file (x.txt) and use IOSTAT in
read command to determine the number of data points to be processed.
Print the number of data points and the maximum and minimum you find.
97,28,66,87,15,95,45,67,76,65,73,88,69,90,63,25,47,70,63,99,61,79,10,92,36,89
前面讀數據的部分我已經解決，問題是如何讀進來後如何用Max和min函數來找最大最小值@@
助教有打一些提示(?)教我們怎麼找

可是這是從螢幕手動輸入的寫法，換成數據我就不太會了，= =還希望版上大神可以幫幫
