Group Statement

∟Group Statement

This section describes what is a group statement in H language.

A group statement is a statement that has multiple sub-statements grouped together to be used as a single statement. A group statement has the following syntax:

(
   statement; 
   ...;
);

If you want to put multiple statements as a single sub-statement in a conditional $if, $elseif or $else statement, you need to use a group statement with the following syntax:

$if condition, (
   statement; 
   ...;
);
$elseif condition, (
   statement; 
   ...;
);
...
$else, (
   statement; 
   ...;
);

Here are example of group statements:

$if price > 1000.00, (
   write("Too expensive for me!");
   ...
);
$elseif price < 100.00, (
   write("I want to buy it!");
   ...
);
$else, (
   write("I will think about it!");
   ...
);

Design options:

1. Use round brackets to specify a group statement:

$if condition, (
   statement; 
   ...;
);

2. Use curly brackets to specify a group statement.

$if condition, {
   statement; 
   ...;
};
