Usage

Equal is strictly a dyadic operator, there must be a value on both sides of the = operator or a VALENCE ERROR will occur. Equal tests the value(s) on the left against the value(s) on the right, and returns 1 for each value that matches, 0 otherwise. Note that unlike the = symbol in a language like C, equal never assigns a value to a variable, it is only used for comparison purposes. For assignment, the Assign symbol is used.

Example

'A'='A'

1

'a'='A'

0

2+2=5

0

1 2 3 4 = 1 0 4 4

1 0 0 1
