4.9.1 Errors Caused by All Compare Instructions
These errors can occur when you are using the compare instructions in a program.
They are logged in the error log.
If this error occurs: Then: Do the following:
The array index is negative. ENO is set according to ERROR_ENO,
and element zero of the array is used for the
instruction's operation.
Specify a valid array element.
The array index is too large. ENO is set according to ERROR_ENO,
and the last element of the array is used for
the instruction's operation.
Specify a valid array element.
4.9.2 Errors Caused by the Limit Instruction
These errors can occur when you are using the LIMIT instruction in a program. They are
logged in the error log.
If this error occurs: Then: Do the following:
The result is larger than what Out's data
type supports.
ENO is set according to ERROR_ENO,
and Out contains the largest signed value
allowed for the data type being used.
Specify a larger data type for Out. For
example, if you are using integers, specify
the data type as a double integer.
Minimum is greater than Maximum. ENO is set according to ERROR_ENO,
and the values for Mn and Mx are swapped
before the limit operation is performed.
Make sure the value for Mx is larger than
that for Mn.
