Note: EndIf marks the end of the Then block that is executed if the condition is true.
If...Then...Else... EndIf Structures
To execute one group of commands if a conditional test is true and a different group if
the condition is false, use this structure:
Ê
Executed only if x>5.
Ë Executed only if x{5.
Ì Displays value of:
• 2x if x>5
• 5x if x
{5
If...Then...ElseIf... EndIf Structures
A more complex form of the If command lets you test a series of conditions. Suppose
your program prompts the user for a number that corresponds to one of four options. To
test for each option (
If Choice=1, If Choice = 2, etc.), use the If...Then...ElseIf...EndIf
structure.
Ê

Ì
:If x>5 Then
: Disp "x is greater than 5"
: 2†x!x
:Else
: Disp "x is less than or
equal to 5"
: 5†x!x
:EndIf
:Disp x
