an array.

For example:

i=101;

will cause unpredictible results.

And :

declare (t(100),i) fixed binary;

i=101;

t(i)=0;

will issue the message : "The SubscriptRange condition was raised." at execution time.

Or, it can be handle by an on-unit.

declare (t(100),i) fixed binary;

i=101;

t(i)=0;

e:on SubscriptRange system; /* default dehaviour */

<br>And the same way for a string,

the StringRange condition is raised when a substring reference is beyond

The Size condition is raised when a numerical value is shorten

as a result of a convertion assigment.
