0 Replies and 1267 Views input from external file  1267  0 Started by  Deleted User Hello everybody, I should assign some input values (constants, file paths) to an IDL program from an external file, without modifying any part of the original code. In other words, I have&160;a .txt file&160;containing my input&160;and&160;a "black box" program, I just know what it needs to work. I think I could try with a script, a .pro batch file, but I can't figure it out. Does anybody has any good idea Thanks for your help, Giuseppe
