Creating a Multi-Statement Function

You can also create a user-defined function whose definition consists of multiple

statements. The definition can include many of the control and decision-making

structures (

If, ElseIf, Return, etc.) used in programming.

Note: For information about similarities and differences between functions and

programs, refer to Programming.

For example, suppose you want to create a function that sums a series of reciprocals

based on an entered integer (

n):

When creating the definition of a multi-statement function, it may be helpful to visualize it

first in a block form.

Func and EndFunc must begin and end the function.

Ë Variables not in the argument list must be declared as local.

Func

Local temp,i

If fPart(nn)ƒ0 or nn{0

Return “bad argument”

0!temp

For i,nn,1,M1

approx(temp+1/i)!temp

EndFor

Return temp

EndFunc
