If test returns a list, commands 1 and commands 2 must return a single object or both must return a list that

is the same size as the list returned by test.

If commands 1 or commands 2 both return a list, each list is the same size and each element is picked from

either commands 1 or commands 2, depending on the outcome of test on the elements of the test list.

CASE

Syntax:

CASE

IF test1 THEN commands1 END;

IF test2 THEN commands2 END;

…

[ DEFAULT commands]

END;

Evaluates test1. If true, executes commands1 and ends the CASE. Otherwise, evaluates test1. If true, executes

commands2 and ends the CASE. Continues evaluating tests until a true is found. If no true test is found,

execute default commands, if provided. The CASE command is limited to 127 branches.

Example:

CASE

IF A<0 THEN RETURN "negative"; END;

IF 0≤A≤1 THEN RETURN "small"; END;

DEFAULT RETURN "large";

END;

IFERR

IFERR commands1 THEN commands2 END;

Executes sequence of commands1. If an error occurs during execution of commands1, executes sequence of

commands2.

NOTE: The error number is stored in the variable Ans. You can use this variable in the commands2 syntax of

the THEN clause of the IFERR command.

IFERR ELSE

IFERR commands1 THEN commands2 ELSE commands3 END;

Executes sequence of commands1. If an error occurs during execution of commands1, executes sequence of

commands2. Otherwise, execute sequence of commands3.

Loop

FOR

Syntax: FOR var FROM start TO nish DO commands END;
