Equivalent Compiler Options

Some compiler directives and compiler options have the same effect, as shown in the table below. However, compiler directives can be turned on and off throughout a program, while compiler options remain in effect for the whole compilation unless overridden by a compiler directive.

The following table shows compiler directives and equivalent command-line compiler options:
