National Language Sort Sequence (NLSS)

NLSS applies only to non-numeric conditional breakpoint expressions of type Char-8.

Non-numeric conditional breakpoint expressions are divided into the following two types:

Char- 8: each character contains 8 bits
Char-16: each character contains 16 bits (DBCS)

The table below shows the possible combinations of non-numeric conditional breakpoint expressions.

The sort sequence table used by the source debugger for expressions of type Char-8 is the sort sequence table specified for the SRTSEQ parameter on the Create CL Module (CRTCLMOD) or Create Bound CL Program (CRTBNDCL) commands.

If the resolved sort sequence table is *HEX, no sort sequence table is used. Therefore, the source debugger uses the hexadecimal values of the characters to determine the sort sequence. Otherwise, the specified sort sequence table is used to assign weights to each byte before the comparison is made. Bytes between, and including, shift-out/shift-in characters are not assigned weights.

Note: The name of the sort sequence table is saved during compilation. At debug time, the source debugger uses the name saved from the compilation to access the sort sequence table. If the sort sequence table specified at compilation time resolves to something other than *HEX or *JOBRUN, it is important the sort sequence table does not get altered before debugging is started. If the table cannot be accessed because it is damaged or deleted, the source debugger uses the *HEX sort sequence table.

Type	Possibilities
Char-8	Character variable compared to character variable Character variable compared to character literal ¹ Character variable compared to hex literal ² Character literal ¹ compared to character variable Character literal ¹ compared to character literal ¹ Character literal ¹ compared to hex literal ² Hex literal ² compared to character variable ¹ Hex literal ² compared to character literal ¹ Hex literal ² compared to hex literal ²
Char 16	DBCS character variable compared to DBCS character variable DBCS character variable compared to graphic literal ³ DBCS character variable compared to hex literal ² Graphic literal ³ compared to DBCS character variable Graphic literal ³ compared to Graphic literal ³ Graphic literal ³ compared to hex literal ² Hex literal ² compared to DBCS character variable Hex literal ² compared to Graphic literal ³
: ¹ Character literal is of the form 'abc'. ² Hexadecimal literal is of the form X'hex digits'. ³ Graphic literal is of the form G'<so>DBCS data<si>'. Shift-out is represented as <so> and shift-in is represented as <si>.
