ST7 Assembler Linker

UM0144

83/92

Currently Unknown Numeric type

An error in your Tabgen File, or a corrupted .TAB file: the numeric handler was asked to

check a number against an undefined numeric type. Are you using the latest version of

ASM.EXE and your .TAB file?

Improper Characters

Unusual characters have been spotted in the source file, of value >127.

Label used before its EXTERN definition

Labels must be declared EXTERNAL before their use, preferably in a group at the top of

the file.

Ambiguous Label Name

The label name in the single-quotes at the end of the error-line can be confused with a

Cannot have DS.X in segments containing code/data! (only for [void] segs!)

DS.X does not produce any code; it simply advances the assembler's notional Program

Counter. It cannot be used in the same segment as real 'code' or data.

Cannot have code in segments previously containing DS.X (only for non-void segs!)

DS.X does not produce any code; it simply advances the assembler's notional Program

Counter. It cannot be used in the same segment as real 'code' or data.

Constant too large for directive 'value'

A DC.B cannot be given an argument >255, for example. Use LOW or OFFSET operators

to truncate any wild arguments.

Couldn't find entry for segment in mapfile

This is for listings produced with '-fi' option. Complex include file structures and empty

segments can sometimes throw the assembler off the track.

COD index only allowed on Introduction

When you're using the multiple linker output file scheme, you can only specify the linker

output file number for a particular class at the time of that class's introduction.

#LOAD before Segment!

The #load has to be but at a given address! Before the first segment the assembler won't

know what address to put it at! Shift the #load after a SEGMENT directive.

#LOAD before Segment!

The assembler had problems finding the file you've named in a #LOAD directive.

All EQUs Involving External args must be before first segment!

Cannot nest #includes > 5 levels

Couldn't find label list in mapfile

Happens with option '-fi' - Implies problem with the mapfile itself, or unsuccessful previous

link, etc.

Couldn't find label in mapfile

As above. Is the Mapfile up to date with your Edits? A label may be declared EXTERN, but

never used.

Couldn't find label in mapfile

The date info has to be stored at a given address - before a SEGMENT there is no

address information for the assembler to work on.
