We have already met most of the new intrinsic functions before. Here, we deal only with their general classification and with those that have so far been omitted.
All intrinsic procedures have keyword arguments:
CALL DATE_AND_TIME (TIME=t)and many have optional arguments. They are grouped into four categories:
Bit inquiry BIT_SIZE Number of bits in the model Bit manipulation BTEST Bit testing IAND Logical AND IBCLR Clear bit IBITS Bit extraction IBSET Set bit IEOR Exclusive OR IOR Inclusive OR ISHFT Logical shift ISHFTC Circular shift NOT Logical complement Transfer function, as in INTEGER :: i = TRANSFER('abcd', 0) (replaces part of EQUIVALENCE) Subroutines DATE_AND_TIME Obtain date and/or time MVBITS Copies bits RANDOM_NUMBER Returns pseudorandom numbers RANDOM_SEED Access to seed SYSTEM_CLOCK Access to system clock
