ASMA049W

Illegal range on ISEQ
Explanation
If this message is accompanied by another, this one is advisory.
If it appears by itself, it indicates one of the following errors: 
An operand value is less than 1 or greater than 80, or the second
operand (rightmost column to be checked) is less than the first operand
(extreme left column to be checked).
More or fewer than two operands are present, or an operand is
null (empty).
An operand expression contains an undefined symbol.
An operand expression is not absolute.
The statement is too complex. For example, it might have forward
references or cause an arithmetic overflow during evaluation.
The statement is circularly defined.

System action
Sequence checking stops.

Programmer response
Supply valid ISEQ operands. Also, be sure that the records following
this statement are in order; they have not been sequence checked.
