For better readability, END statements must have the same indentation level as their matching opening PROCEDURE,
SELECT, and DO statements.
This rule does not verify the alignment of the compound statements DO ... END; (type 1) and BEGIN ... END;. They are
mostly used together with the IF and ON statements and are subject to different indentation rules.
Noncompliant code example
foo: proc options(main);
declare i fixed decimal init (0);
do i = 0 to 9;
if i = 0 then /* The do was forgotten here */
put list ('Initialization...');
put list ('i = 0');
end; /* Non-Compliant - should be aligned with the DO statement */
end; /* Non-Compliant - should be aligned with the PROCEDURE statement */
/* The procedure's end seems to be missing */
Compliant solution
foo: proc options(main);
declare i fixed decimal init (0);
do i = 0 to 9;
if i = 0 then do;
put list ('Initialization...');
put list ('i = 0');
end; /* This end's alignment is not verified by this rule */
end; /* Compliant */
end; /* Compliant */
