## Limits

The only built-in limit is on the number of lines of test data that may be used when the selected program does filename globbing. Because the only way to exercise the regular expression matching facilities of such programs is to create files whose names are the test items, it is undesirable to allow large numbers of test items. This is not only slow, but by using large numbers of inodes, the supply of which is limited, may interfere with the normal functioning of the system. A limit of 500 lines of test input is therefore imposed. More than 500 lines of test data may be created, but the regular expression will not be executed if this limit is exceeded. Even this limit may be changed via the command ShellItemLimit in the initializatin file.
