in sequence. {statement1} is skipped if the condition to the left of the
S
command is false, and then {statement2} and everything after it is executed.
Syntax

: A non-zero evaluation result of the condition to the left of the
S
command is interpreted as “true”, so {statement1} is executed, followed by
{statement2} and everything after it in succession. A zero evaluation result
of the condition to the left of the
S

{statement1} is skipped, and {statement2} and everything after it is executed.
