You can control the flow of script execution by using the following types of statements to manage the order in which operations are executed:.

...

...

...

...

Use conditional statements (if, else, else if, switch)

...

IF statements

IF statements

The IF statement works as follows: if the test condition is true, the statement is executed.

...

if ( 2 < 3 )
 {
 string $blah = "This worked";
 print ($blah);
 }

...

ELSE statements

The ELSE statement always follows the IF statement. The ELSE statement is executed when the preceding IF statement is false.

...

if (5 % 2 >1)
 {
 print "bah";
 }
 else
 {
 print "humbug";
 }

ELSE IF statements

ELSE IF statements

The ELSE IF statement is always paired with the IF conditional statement. Unlike the else command which executes a statement when the IF statement is false, the ELSE IF statement requires another test condition to be true, or it will not execute either statement.

...

if (-1 >= 1)
 {
 print "Statement 1";
 }
 else if (-1 <= 1)
 {
 print "Statement 2";
 }

SWITCH statements

SWITCH statements

The switch statement is a conditional statement that executes a code block depending on which one of a number of given cases is matched to the switch expression.

...

WHILE statements

WHILE statements

A WHILE looping statement continuously executes designated statements as long as a specific condition remains true.

...

int $PJ = 5;
  while ($PJ > 0)
 
  {
     print
     ("There are " + string($PJ) + " P.J. sandwiches left.");
  
  $PJ = $PJ - 1;
    }
  print ("Houston, we have a problem!");

...

DO WHILE statements

A DO WHILE looping statement executes a specific statement then checks whether or not to repeat the loop. This ensures that the statement is executed at least once.

...

int $peanuts = 1;
 do {
 print ("Elephants work for peanuts");
 $peanuts += 1;
 print ($peanuts);
 }
 while ( $peanuts < 10);

...

FOR statements

A FOR looping statement provides loop control that has initialization, test, and an increment statement.

...

//Define the statement you are going to print each iteration
 string $statement;
//Define variables to use as counters
 int $i, $ j;
//Start the $i loop and specify start, end, and amount to increment
 for( $i = 1; $i < 6; $i += 1 ) {
//Start the $ j loop and specify start, end, and amount to increment 
   for( $j = 1; $j < 15; $j += 2 ) {
//Tell Shogun Post to print something if $i < $J

    if( $i < $j )
   
   $statement = string( $i ) + " is less than " + string( $j );
//Tell Shogun Post to print something else if $i > $j

    else if( $i > $j )
       $statement = string( $i ) + " is greater than " + string( $j );
//Tell Shogun Post what to print if the two counters are equal
     else
 
     $statement = "This is what happens when things coincide";
//Tell Shogun Post to actually print the statement you've assembled
   print( $statement );
//Close the second loop
   }
//Close the first loop
 }

// Initialize Variables
print " ";  
// Create array of children under 'Actor' Mary's character node
string $childarray[] = `getChildren Mary`;    
// Determine # of children
int $childcount = `getCount $childarray`;  
// Create a $childarrayloop to hold a number 
int $childarrayloop = 0;  
// Print an empty string
   string $ proptest;
// Start a loop which run once for each of Mary's children
for ( $childarrayloop=0 ;
 $childarrayloop < $childcount ;
 $childarrayloop +=1 ){
  
 // print name of current child marker in array     
  print ( string ($ childarray[$childarrayloop] ) );
    // return the name of the marker and compare the name 
    // of the marker to the name"LFWT"
  
 $ proptest = ` getStringProperty $ childarray[$childarrayloop] Name`; 
    if ($ proptest==LKNE){
  
     // if that LFWT marker is found, this tells the loop to quit
        $ childarrayloop=$childcount; 
        print ( "EXITING LOOP" );
      
 }
   
}

Use interruption statements (break)
