The following is a brief summary of the basic functions in MEL.


print - Prints any given text string in the Scripting Window

print(text string)
example:
print("Hello!!");

if - Test if something is true and execute a piece of code

if([test clause]){
...stuff to execute if [test clause] is true
}
example:
if($i == 1){

	print("i equals 1");

}

if-else - Test if something is true and execute a piece of code, otherwise execute something else

if([test clause]){
...stuff to execute if [test clause] is true
}else{
...stuff to execute if [text clause] is false
}
example:
if($i > 0){

	print("i is positive");

}else{

	print("i is negative");

}

while - Loop and execute a function, continue looping until a test clause proves false

while([test clause]){
...stuff to execute

[increment counter]
}
example:
$i = 0;

//loop ten times
while($i < 10){
	
	//print number
	print($i);
	
	//increment counter
	$i++;
 
}


for - Same as while loop, but the syntax requires that a counter increment (or some other statement) be performed each step.

for([initialization statement];[test clause];[statement for each step]){
...stuff to do
}
example:

//loop ten times
for($i=0;$i < 10;$i++){
	//print number
	print($i);
	
	
	
}
