The ELSE Instruction


ELSE identifies the instruction to be run if the expression is false.  To 
tell the interpreter to select from one of two possible instructions, use: 

IF expression
 THEN instruction1
ELSE instruction2

You could include the IF-THEN-ELSE format in a procedure like this: 

IF answer = 'YES'
 THEN SAY 'OK!'
ELSE SAY 'why not?'
Try the next example, GOING.CMD, to see how choosing between two 
instructions works. 

/* Using IF-THEN-ELSE */
SAY "Are you going to the meeting?"
PULL answer
IF answer = "YES"
 THEN
 SAY "I'll look for you."
ELSE
 SAY "I'll take notes for you."
EXIT

When this procedure is run, this is what you will see on your screen: 

[C:\]GOING
Are you going to the meeting?

yes

I'll look for you.

[C:\]
