The I Function: Index Generator, Index of

Monadic (One-Argument) Form: Index Generator I B

Dyadic (Two-Argument) Form: Index of A I B

The index offunction result is the index of the first occurrence in argument A of

the element(s1 in argument B. Argument A must be a vector. Argument B can be

a scalar, vector, or array. The result is the same shape as argument B. If the element

in argument B cannot be found in argument A, the value of the index for that ele-

ment is one greater than the largest index of A (nl0 + PA):

The index generator function result is a vector containing the first B integers, start-

ing with the index origin (see Dl0 system variable in Chapter 5). The argument can

be a nonnegative integer that is either a scalar or a single-element array.

5.t i 5 -Each of the generated integers is added to 5.

Note: The result of the I function depends on the 010 system variable (see Chapter

5 for information on the 010 system variable).
