integer

the conditions under which the assembler issues various warning messages pertaining to the USING instructions used in the source program. The permissible value for integer is in the range 1 to 15.

Several conditions can be combined by adding together the associated condition numbers. For example, specifying WARN(12) instructs the assembler to issue warning diagnostic messages for the conditions with condition numbers 4 and 8.

The meaning of the various condition number values for integer are:

1

the assembler issues message:

• ASMA300 when a earlier active ordinary (unlabeled) USING's range coincides with and supersedes that of the USING being processed.
• ASMA301 when the range of the USING being processed coincides with and supersedes that of a earlier active ordinary (unlabeled) USING.
• ASMA306 when the range of the USING being processed coincides with the implicit USING 0,0 (for example USING 0,2).

2

the assembler issues message ASMA302 when a USING specifies R0 as a base register, with a non-zero absolute or relocatable expression for the base address.

4

Multiple resolutions: The assembler issues message:

• ASMA303 when multiple resolutions are possible for an implicit address.
• ASMA306 when the range of the USING being processed overlaps the range of the implicit USING 0,0 (for example USING 16,2).

8

the assembler issues message ASMA304 when the calculated displacement in any valid resolution exceeds the threshold specified in the LIMIT suboption.

NO

no USING warning messages are issued.

Default

WARN=15
