[b]IF[/b] [i]Condition[/i] [[b]THEN[/b] | [b]GOTO[/b]] [[i]Label[/i] | [b]EXIT[/b]] 

<SPAN class=hd3>Function 
Evaluate [i]Condition[/i] and, if it is true, jump to the point in the program designated by [i]Label[/i].


<UL>
<LI value=1>[b][i]Condition[/i][/b]  is a simple statement, such as "x = 7" that can be evaluated as True or False. 
<LI value=2>[b][i]Label[/i][/b]  specifies where to go in the event that [i]Condition[/i] statement evaluates as True. </LI></UL>

<SPAN class=hd3>Explanation 
[b]IF...THEN[/b] is decision maker that affects program flow. It tests a [i]Condition[/i] statement and, if that statement is True, goes to a point in the program specified by [i]Label[/i]. The available comparison operators are: 

<CENTER>
[table  cellSpacing=0 cellPadding=4 border=1]
[tr ][td  align=middle width=130 bgColor=#cfcfcf]Comparison Operator[/td][td  align=middle width=170 bgColor=#cfcfcf]Definition[/td][/tr][tr ][td  align=middle]=[/td][td  align=middle]Equal[/td][/tr][tr ][td  align=middle]&lt;&gt;[/td][td  align=middle]Not Equal[/td][/tr][tr ][td  align=middle]&gt;[/td][td  align=middle]Greater Than[/td][/tr][tr ][td  align=middle]&lt;[/td][td  align=middle]Less Than[/td][/tr][tr ][td  align=middle]&gt;=[/td][td  align=middle]Greater Than or Equal To[/td][/tr][tr ][td  align=middle]&lt;=[/td][td  align=middle]Less Than or Equal To[/td][/tr][/table]</CENTER>
Comparisons are always written in the form: [i]Variable Op Value[/i].


<UL>
<LI value=1>[b][i]Variable[/i][/b]  is a bit, byte or word variable. 
<LI value=2>[b][i]Op[/i][/b]  is the comparison operator. 
<LI value=3>[b][i]Value[/i][/b]  is a variable or constant for comparison. </LI></UL>



Main:
  [b]IF[/b] StartBtn = 1 [b]THEN[/b] Main 			' wait for input to go low


Check_Mode:
  [b]IF[/b] ModePin = 0 [b]GOTO[/b] Show_AMPM 		' use HH:MM xM format if mode = 0
</PRE>

Some programmers may prefer a more verbose style; the following syntax is also supported:

Check_Mode:
  [b]IF[/b] ModePin = 0 [b]THEN GOTO[/b] Show_AMPM 		' use HH:MM xM format if mode = 0</PRE>
 </PRE>
This is what is in my online help file. Perhaps I have an outdated copy?
