CATC Scripting Language for Bluetooth Analyzers

CATC

Manual Ver. 1.21

The above expression will evaluate to “Greater than or equal to 5” because the first
true expression is

x >= 5

. Note that a semicolon is required at the end of a

select

expression because it is not a compound statement and can be used in an

expression context.

There is also a keyword

default

, which in effect always evaluates to true. An

example of its use is

Astring = select {

A == 1 : "one";

A == 2 : "two";

A == 3: "three";

A > 3 : "overflow";

default : null;

};

If none of the first four expressions evaluates to true, then

default

will be eval-

uated, returning a value of

null

for the entire expression.

select

expressions can also be used to conditionally execute statements, similar

to C

switch

statements:

select {

A == 1 : DoSomething();

A == 2 : DoSomethingElse();

default: DoNothing();

};

In this case the appropriate function is called depending on the value of A, but the
evaluated result of the

select

expression is ignored.
