... This program demonstrates While, Do, and For loop counting using
... user-designated start, stop, and increment values.

Function Main
    Declare Integer start
    Declare Integer stop
    Declare Integer increment
    
    Assign start = GetValue("starting")
    Assign stop = GetValue("ending")
    Assign increment = GetValue("increment")
    Call WhileLoop(start, stop, increment)
    Call DoLoop(start, stop, increment)
    Call ForLoop(start, stop, increment)
End

Function GetValue (String name)
    Declare Integer value
    
    Output "Enter " & name & " value:"
    Input value
Return Integer value

Function WhileLoop (Integer start, Integer stop, Integer increment)
    Output "While loop counting from " & start & " to " & stop & 
        " by " & increment & ":"
    Declare Integer count
    
    Assign count = start
    While count <= stop
        Output count
        Assign count = count + increment
    End
End

Function DoLoop (Integer start, Integer stop, Integer increment)
    Output "Do loop counting from " & start & " to " & stop &
        " by " & increment & ":"
    Declare Integer count
    
    Assign count = start
    Loop
        Output count
        Assign count = count + increment
    Do count <= stop
End

Function ForLoop (Integer start, Integer stop, Integer increment)
    Output "For loop counting from " & start & " to " & stop &
        " by " & increment & ":"
    Declare Integer count
    
    For count = start to stop step increment
        Output count
    End
End
