ZLINK Errors

Explanation

Aborting Link

This message occurs when the Q command is entered to terminate the link.

nnn error(s) detected during link

This is a final status reporting on the total number of errors that were detected during the link.

Unknown runstring file suffix: aaaa

The runstring file suffix for ZLINK must be 'ZLNK'.

Unknown command xxx - ignored

Command xxx is not a valid command for ZLINK. Check the section on available commands.

Duplicate NAM entry: name

NAM name is already in symbol table. That is, another relocatable module has the same NAM name.

Symbol table overflow

Symbol table for ZLINK does not have enough space to fit all the required entry points and NAM records. If this error occurs it may be necessary to reduce either the number of modules, or the number of entry points within the modules.

Can't find NAM: name in PASS 2

This error should not occur if PASS 1 was successful. It indicates an internal inconsistency in ZLINK.

External reference table overflow

Too many external references in this module. The limit is currently set at 500 per module.

Undefined EXTernal label: name

External reference made to this name but no entry point has been found.

Undefined default external DEXT: name

Neither of the names referred to in a DEXT statement have been found.

Duplicate entry point name: name

Same subroutine name defined in two or more modules, or multiple times in the one module.

Not used

Unrecognized subelement in code element

Refer to Appendix A, on relocatable code records, under element types 1 and 2. This error should not occur - it indicates an internal inconsistency in ZX80R or ZLINK.

Expression evaluation error

Illegal combination of operators and operands in a module. These errors are usually should picked up by ZX80R and should not occur.

Unknown code element type

The code element type generated by ZX80R should be 0, 1, or 2. This error indicates an internal inconsistency in either ZX80R or ZLINK, and should not occur.

Code segment length error

The element length in the relocatable code records, as generated by ZX80R is incorrect. This error indicates an internal inconsistency in either ZX80R or ZLINK, and should not occur.

Duplicate NAM record in module: name

Current module has already supplied a NAM record. This error is not expected as ZX80R will only generate modules with 1 NAM record.

Not used

Linkage forced with errors

The FO command has been used to force the link in spite of unresolved external references or other errors.

Link terminated due to errors

There are either unresolved external references or other errors in the link, and thus it is terminated without creating a program file.

Unable to complete link due to undefined externals

External references are not defined in the ZLINK file. ZLINK does not create the executable file.

Not used

Library command not implemented

The LI command is not yet available in the ZLINK linker program.

Missing parameter in ORG command

The ORG command requires that the origin address is also entered.

Illegal alignment mask specified

The alignment mask must be a power of 2.

Missing END record for module xxxxx

Each module must have an END record. The END record is automatically generated by ZX80R so this error should not occur unless ZX80R terminates abnormally.

Unknown record type ignored in relocatable file

The record types (as documented in Appendix A, under New Formats) must be 0 - 12.

Unknown entry point type for: name

An entry point of type not 0 (absolute) or 1 (relocatable) was detected for the specified name. Inconsistency between ZX80R and ZLINK.

Align record detected before NAM record

The NAM record sets up the environment for the rest of the module. The Align record cannot be processed before the NAM record. That is, the NAM record should appear at the beginning of the program.

End record detected with no NAM record

NAM and END records in the relocatable code must be in matching pairs. As ZX80R should trap this error, it indicates an internal inconsistency in either ZX80R or ZLINK.

Illegal logical origin specified

The logical origin must be between 0 and FFFF inclusive.

Illegal file type nn

The relocatable file must be of type 11.

Illegal origin(s) specified on PO command

Either the logical address is out of range 0 to FFFF, or the physical address is out of range 0 to 7FFFF.

Link NAME not defined

No NAM record in link command file. In interactive mode, the NAM command must be used.

Break detected

ZLINK can be terminated by an operator break.

Link name not defined

The NAM command has been used without specifying the link name.

Entry point name not found in PASS 2.

This error indicates an internal inconsistency in either ZX80R or ZLINK.

ORG symbol must be predefined and absolute

The symbol used to specify ORG must be defined as an external within a previously relocated module and must not be relocatable themselves.

Not used

Assembly errors in module: name

Unable to link this module because it has assembly errors. Fix the errors, recompile, and try again.

Relocation overflow in module NNNNNNNN

The limit specified in the optional second parameter of the OR command has been exceeded in relocating code. This usually means that a code module is too large, or that too many modules have been linked together.
