Hi, I am having a bit of trouble trying to record the output from my code and any help is highly appreciated. Attached is the code that needs to be looked into (changed extension to .txt from .f as PF wouldn't allow it) and a screenshot of output that I am trying to record. What I am trying to do is collate the XMIN (1), XMIN(5) and XMIN(9) together with C(1) output. Similarly, I need to do the same with XMAX and AMP outputs. I tried adding the FORMAT and WRITE statements towards the relevant section (now commented out) to do the needful, however there is still no record of it in any of the files propeq.dat, propeq.dat1 and integrate.csv as asked by Fortran to open when running the code. Please assist me. Thank you for taking your time!
