There is just one character operator, //, denoting the concatenation of two strings. A substring notation may be used to specify part of a character string. The relational operators are • < (less than) • <= (less than or equal) • == (equal) • / = (not equal) • > ...

I follow step by step in https://software.intel.com/en-us/articles/migrating-from-compaq-visual-fortran but when build, the error about the compiler does not regconize the operator "<>" (NEG) is displayed. When I change all the error point from <> to ...

If a value is specified, there can be no spaces on either side of the equal sign. If no value is specified, the default value is 1. Compare to the -U identifier option. By default, macros are not expanded in Fortran source statements. Use the -F option to enable macro expansion i...

The characters are transferred to the variables without any conversion of data, and may not be portable. Character expressions which include the // operator can be assigned only to items of type CHARACTER. Here, the v is the name of a variable, substring, array element, or record field of...
