You can control the scope of script execution by grouping statements into a block. The contents of a group cannot be referenced outside of the block.
Grouping commands is useful if you want to:

• Use a single statement to execute a group of statements in the desired order
• Create script modularity
• Define the visibility of local variables

You group statements by declaring a block within braces ({}):

For example:

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

Grouping examples

This example groups the statement to be executed for an IF conditional statement:

float $MasterControl = 1;
float $MarkerControl = 1;
 if ($MasterControl == 1 || $MarkerControl == 1)
 {
 select LFWT;
 findTail 2;
 cutKeys;
 print ("Operation was run.");
 }
