NAT0884: Internal error, save area chain destroyed.

Text	Internal error, save area chain destroyed.
Expl.	The relocatable save area in Natural is destroyed. Natural resets the chain and restarts. Natural always tests the correct chains of its save areas. The error is caused by a wrong register 13, a save area overflow, or a wrong relocated user area. One reason for a save area overflow may be too many recursive program calls.
Actn.	Natural corrects automatically and restarts. If need be, reduce the number of recursive program calls.

NAT0885: Internal error, I/O buffer overwritten.

Text	Internal error, I/O buffer overwritten.
Expl.	The buffer area that is used to generate output to the screen/printer is also used for other purposes. A condition has arisen where the contents of this I/O buffer have been destroyed, and the buffer has not been re-initialized.

NAT0886: Storage overflow in extended buffer.

Text	Storage overflow in extended buffer.
Expl.	Certain tables during processing and compilation of Natural programs are stored in the extended buffer.

Actn.	Reduce size of source program, or contact your Natural administrator.

NAT0887: Internal stack overflow.

Text	Internal stack overflow.
Expl.	Excessive program recursion has caused an internal overflow of the program-storage stack during program execution.
Actn.	Reduce the number of nested subroutines; or contact your Natural administrator.

NAT0888: Storage overflow during compilation or execution.

Text	Storage overflow during compilation or execution.
Expl.	This error is caused by an overflow situation: - At compilation time, this error is issued if the length of an arith- metic expression in an IF condition exceeds the maximum of 32 KB. - At execution time, this error is due to a relocation of the DATSIZE buffer at execution of a Natural subprogram from a 3GL program (Natural 3GL program interface).
Actn.	Compilation: Reduce the number of arithmetic operations in the condition. Execution: Use the CALLNAT interface INTERFACE4.

NAT0890: Invalid source parameter construction.

Text	Invalid source parameter construction.
Expl.	A possible cause for the error is the construction of a parameter source notation within another source parameter. Natural supports only one level of parameter source processing.
Actn.	Check program and correct error.

NAT0894: Invalid format/length for operand.

Text	Invalid format/length for operand.
Expl.	An invalid format/length definition is used for an operand. This can have the following reasons: MINVAL/MAXVAL: The combination of operands with their format/length definitions does not comply with the rules for the generation of intermediate formats. Use the IR clause to set a certain format/length as result.
Actn.	Change the format/length of the operands.

NAT0899: Internal error in structure of DDM :1:.

Text	Internal error in structure of DDM ....
Expl.	The DDM was not correctly generated and contains an internal inconsistency.
