Instructions
Format Definition Result
IMAG( x)
imaginary part b, for x = a + ib
I,R,C to R
For integer arguments, the result is zero. Results are single precision real.
For real arguments, the result is zero. Resultant precision is the same as the
argument.
For complex numbers, the result is the imaginary component, with precision
equal to that of the argument.
IMPL(,) xy numeric implication I,R,C to L
The result is FALSE if the first argument is negative and the second is positive
or zero. The result is true otherwise.
INDEX( a1, a2)
start position of a2 in
a1
2 = INDEX(’ABC’,’B’) A to I
INDEXSTR start position of a2
( a1, a2, x1, x2)
from x1 to x2 in a1
The result is zero if the second string is not found in the first string.
A,I to I
Arguments 1 and 2 must be character strings.
Arguments 3 and 4 must be numeric values. Prior to use as substring subscripts,
both arguments are converted to integers and checked for range of 1 to 80.
If the lower string subscript is less than 1, it is changed to 1. If the upper string
subscript is greater than 80, it is changed to 80.
The larger string subscript value becomes the upper substring subscript.
The result is zero if the second string is not found in the substring of the first
string.
INT( x)
type to I largest integer in abs ( x)
with
sign of x
I,R,C to I
For complex arguments the function is applied to the real component.
ITOL( x)
type to L TRUE, if x < 0
FALSE, if x ≥ 0
LEQ(
a1, a2)
lexical
TRUE, if a1 = a2
equality
FALSE otherwise
LGE(
a1, a2)
lexical greater
TRUE, if a1 ≥ a2
than or equal to
FALSE, if a1 < a2
LGT(
a1, a2)
lexical greater
TRUE, if a1 > a2
than
FALSE, if a1 ≤ a2
LLE(
a1, a2)
lexical less
TRUE, if a1 ≤
a2
than or equal
FALSE otherwise
