Can this be done?</DIV> Fri, 05 Mar 2004 03:04:48 GMT stearns 2004-03-05T03:04:48Z https://community.intel.com/t5/Intel-Fortran-Compiler/Character-to-Real-conversion-Fortran90/m-p/766826#M20540 <DIV>I have a program that scans a text file and finds strings in a certain column that look like numbers, ie 100.3, it grabs these strings and prints them out.Now I want to use the same routine, but once the character string is found, ie 100.3, I would like to assign it to a real variable so I can use it in a math expression..
