FORTRAN 77 Language Reference


For a declaration such as LOGICAL H, the variable H is usually one INTEGER*4 element in memory, interpreted as a single logical value. Specifying the size is nonstandard. @

If you do not specify the size, a default size is used. The default size, for a declaration such as LOGICAL Z, can be altered by compiling with any of the options -dbl, -i2,-r8, or -xtypemap. See the discussion in Chapter 2 for details.
