SETA Instruction
| The logical-expression format encloses the function and operands in
| parentheses. In the unary format, the function is followed by the one operand.
| In the binary format, the function is placed between the two operands. For
| both unary and binary formats, the function is separated from the operand or
| operands by spaces.

| (A OR B) and (&J SLL 2) are examples of binary logical-expression format
| functions, and (NOT C) and (SIGNED &J) are examples of unary
| logical-expression format functions.
| The function-invocation format has the function first, followed by one or more
| operands in parentheses.

| FIND('abcde','d') is an example of a function-invocation format. (The
| equivalent logical-expression format is ('abcde' FIND 'd').)
| Spaces are not allowed between the arguments of functions in
| function-invocation format.
| In either format, the operand is an expression of the type expected by the built-in
| function. (The particular details of the number of operands and the operand type
| are provided with the information for each built-in function.)
| Some functions are available in one format, some are available in both. Figure 99,
| which provides a summary of all the built-in functions, shows the forms in which a
| function is available.
