Description

This option tells the compiler to apply FORTRAN 66 semantics when interpreting language features. This causes the following to occur:

• DO loops are always executed at least once

• FORTRAN 66 EXTERNAL statement syntax and semantics are allowed

• If the OPEN statement STATUS specifier is omitted, the default changes to STATUS='NEW' instead of STATUS='UNKNOWN'

• If the OPEN statement BLANK specifier is omitted, the default changes to BLANK='ZERO' instead of BLANK='NULL'

Linux and Mac OS: -66
Windows: None
