If both arguments are zero, then the result is zero.
If x1 and x2 are real and:
x1 = 0 and x2> 0,
then the result is 0.
x1 = 0 and x2< 0,
then the result is π.
x1> 0 and x2 = 0,
then the result is π ⁄ 2 .
x1< 0 and x2 = 0,
then the result is – π ⁄ 2 .
If x1 and x2 are complex ( x1 = a + bi and x2 = c + di)
and:
a = b = 0 and (sign of c) = (sign of d),
then the result is 0.
a = b = 0 and ( sign of c)
≠ ( sign of d)
, then the result is π.
(sign of a) = (sign of b) and c = d = 0 , then the result is π ⁄ 2 .
( sign of a)
≠ ( sign of b)
and c = d = 0 , then the result is – π ⁄ 2 .

For real arguments, the following must be true: x1 > x2 and x2 ≠ 0.
If x1 and x2 are complex ( x1 = a + bi and x2 = c + di)
and:
a = b = 0 and (sign of c) = (sign of d),
then the result is 0.
a = b = 0 and ( sign of c)
≠ ( sign of d)
, then the result is π.
(sign of a) = (sign of b) and c = d = 0 , then the result is π ⁄ 2 .
( sign of a)
≠ ( sign of b)
and c = d = 0 , then the result is – π ⁄ 2 .
Instructions
CHAR( x)
character value See note below. I to A
The function takes the processor collating sequence equivalent (e.g., ASCII or
EBCDIC) of a character and converts it to the character value. The integer value
must be within the range 1 to n – 1 , where n = 2 .
CLEN( c)
character length Character string length in
multiples of 4.
CLOCK( ) CPU time in sec. since
