Hey guys, new here and was hoping for some help. Basically I have to use Fortran 77 to complete some questions for an assignment The first thing to do is, read a bunch of numbers in a list format and then use these numbers to be entered within an equation. The values I have are listed in a 1 column list eg 4.5252 4.541 5.522 etc The equation I have is: XYZ (Where Z are the each value from that list, and X/Y are other values). I need to calculate an answer for each Z value. So far, I'm stuck on even being able to read the file in the first place! My code: Code (Fortran): PROGRAM Example IMPLICIT NONE INTEGER n REAL phi(10) OPEN(10,FILE='data.txt', FORM='FORMATTED', STATUS='OLD') phi=0.0 n=0 DO READ(10,*,END=10) phi n=n+1 ENDDO 10 CONTINUE PRINT*, phi END When I compile the code just reads 0 for some reason. Someone help?
