nn
Specify, in the range of 0 - 99, the maximum number of T2 records (whose length is longer than the length specified on the second parameter) that are ignored (suppressed) and not regarded as errors.

If the number of generated T2 records exceeds the threshold value, all T2 records are regarded as errors.

This option is effective only for HISAM, HDAM, HIDAM, PHDAM, and PHIDAM databases.

ll
Specify, in the range of 1 - 99, the maximum length of T2 that is not regarded as an error.

This option is effective only for HDAM and HIDAM databases. The option, if specified for a HISAM database, does not cause an error, but is ineffective.

Default value
T2CHK=(0,7)
