IBM 5100 - The = Function: Equal to

68
The = Function: Equal To [J
Monadic (One-Argument) Form
There is no monadic form.
Dyadic (Two-Argument) Form: Equal To A=B
The equal to function result is 1 when the value of argument A equals the value
of argument
B; otherwise, the result is O. The arguments (numeric or character)
can be scalars, vectors, or other arrays. The arguments must be the same shape,
unless one of the arguments
is a scalar or any single-element array. Arguments
of the
same shape have the same shape result:
0::::5
()
1,65~321=1,65~321
1
1:::: I A I
o
.' A I:::: 'B'
o
':1. ':::::1.
o
:I.
o
o 0
If one argument is a scalar or a single-element array, the shape of the result is the
same
as that of the other argument. The single element is applied to every element
of the multielement array.

Note: If the arguments are numeric, the result of the = function depends on the
OCT system variable (see Chapter 5 for information on the OCT system variable).
