-Description:

-returning 0 on success or a non-zero error code (`ENOSYS' if the system
-does not provide `gethostname(2)').
-

-
-IChar: `INTEGER(KIND=1)' function.
-
-C: `CHARACTER'; scalar; INTENT(IN).
-
-Intrinsic groups: (standard FORTRAN 77).
-
-Description:
-
- Returns the code for the character in the first character position
-of C.
-
- Because the system's native character set is used, the
-correspondence between character and their codes is not necessarily the
-same between GNU Fortran implementations.
-
- Note that no intrinsic exists to convert a printable character
-string to a numerical value. For example, there is no intrinsic that,
-given the `CHARACTER' value `'154'', returns an `INTEGER' or `REAL'
-value with the value `154'.
-
- Instead, you can use internal-file I/O to do this kind of conversion.
-For example:
-
- INTEGER VALUE
- CHARACTER*10 STRING
- STRING = '154'
- READ (STRING, '(I10)'), VALUE
- PRINT *, VALUE
- END
-
- The above program, when run, prints:
-
- 154

-Description:

-STRING_A and STRING_B are interpreted as containing ASCII character

-set, the result is processor dependent.
-
- If the STRING_A and STRING_B are not the same length, the shorter is
-compared as if spaces were appended to it to form a value that has the
-same length as the longer.
-
- The lexical comparison intrinsics `LGe', `LGt', `LLe', and `LLt'
-differ from the corresponding intrinsic operators `.GE.', `.GT.',
-`.LE.', `.LT.'. Because the ASCII collating sequence is assumed, the
-following expressions always return `.TRUE.':
-
- LGE ('0', ' ')
- LGE ('A', '0')
- LGE ('a', 'A')
-

-as they are not necessarily evaluated assuming the arguments use ASCII
-encoding:
-
- '0' .GE. ' '
- 'A' .GE. '0'
- 'a' .GE. 'A'
-
- The same difference exists between `LGt' and `.GT.'; between `LLe'
-and `.LE.'; and between `LLt' and `.LT.'.

- NInt(A)
-
-NInt: `INTEGER(KIND=1)' function.
-
-A: `REAL'; scalar; INTENT(IN).
-
-Intrinsic groups: (standard FORTRAN 77).
-
-Description:
-
- Returns A with the fractional portion of its magnitude eliminated by
-rounding to the nearest whole number and with its sign preserved,
-converted to type `INTEGER(KIND=1)'.
-
- If A is type `COMPLEX', its real part is rounded and converted.
-
- A fractional portion exactly equal to `.5' is rounded to the whole
-number that is larger in magnitude. (Also called "Fortran round".)
-
- *Note Int Intrinsic::, for how to convert, truncate to whole number.
-
- *Note ANInt Intrinsic::, for how to round to nearest whole number
-without converting.

-
-Rand: `REAL(KIND=1)' function.
-
-FLAG: `INTEGER'; OPTIONAL; scalar; INTENT(IN).
-
-Intrinsic groups: `unix'.
-
-Description:
-
- Returns a uniform quasi-random number between 0 and 1. If FLAG is
-0, the next number in sequence is returned; if FLAG is 1, the generator
-is restarted by calling `srand(0)'; if FLAG has any other value, it is
-used as a new seed with `srand'.
-
- *Note SRand Intrinsic::.
-
- _Note:_ As typically implemented (by the routine of the same name in
-the C library), this random number generator is a very poor one, though
-the BSD and GNU libraries provide a much better implementation than the
-`traditional' one. On a different system you almost certainly want to
-use something better.
