It's difficult to tell from the photos, but this is a rather old book published in 1990, so it shows signs of deterioration such as yellowing and fading. There are no signs of heavy use, and it appears there are no markings when quickly flipping through the pages, but I haven't checked in detail, so I cannot guarantee this. Please understand this beforehand. - Title: Comprehensive Study of FORTRAN Heisei 2nd Year Information Processing Examination Passing Seminar (Type 2) - Author: Kenji Ushizawa - Published: 1990 - ISBN: ISBN4-87408-675-6 Thank you for looking.
