Appendix C. Errors and Warnings
The warning and error numbers emitted by JWasm differ from Masm's. However, the texts of the messages are pretty much identical.As in Masm, the first digit shows the severity of the issue: range 1xxx reports a fatal error ( assembly process is stopped ), range 2xxx indicates an error ( assembly process continues, but no object module will be created ) and 4xxx are warnings.
| x029 | Multiple base registers not allowed | In 16-bit code, one cannot use both BX and BP in indirect addressing; in 32/64-bit code, ESP/RSP can only appear once in indirect addressing. | |
| x030 | Instruction or register not accepted in current CPU mode | ||
| x031 | Invalid addressing mode with current CPU setting | ||
| x032 | Cannot use TRn-TRn with current CPU setting | The TRx special registers were restricted to 80386 and 80486 cpus. | |
| x033 | Must be index or base register | ||

| x035 | |||
| x036 | Scale factor must be 1, 2, 4 or 8 | ||
| x037 | Cannot be used as index register: <register> | Index registers are restricted. In 16-bit mode, only SI and DI can be index registers. In 32-bit mode, all general-purpose registers except ESP can be index registers. | |
| x038 | Base and index register differ in size | ||
| x039 | Expecting comma | ||
| x040 | ORG needs a constant or local offset | ||
| x041 | POP CS is not allowed | ||

| x046 | Prefix must be followed by an instruction | ||
| x047 | Syntax error: Unexpected colon | ||
| x048 | Operands must be the same size: <size op1> - <size op2> | ||
| x049 | Invalid instruction operands | ||
| x050 | Jump distance not possible in current CPU mode | Jcc instructions won't accept type coercions that increase the jump distance (i.e. "jz NEAR PTR label") if current cpu is < 80386. | |
| x051 | Immediate data out of range | ||
| x052 | Can not use short or near modifiers with this instruction | ||
| x053 | Jump out of range by <num> byte(s) | A short distance must be in the range -128 to +127. | |

| x064 | Operand is expected | ||
| x065 | Constant expected | A constant (numeric) value is expected in the current context. Note that a label - more exactly: the offset part of a label's address - is not a constant value, since the final value is calculated by the linker ( or the OS loader ) only. | |
| x066 | Constant operand is expected | The expression evaluator accepts a constant only in the current context. | |
| x067 | .ELSE clause already occured in this .IF block | An .IF block may contain 0 or 1 .ELSE clauses and it must be the last clause before .ENDIF. | |

| x069 | Segment, group or segment register expected | The operand before the colon operator (:) must be a segment, group or segment register. | |
| x070 | Identifier too long | Identifer names are restricted to 247. This is a hard limit for OMF output format. For other formats, the limit may be extended by adjusting and recompiling the source code. | |
| x071 | Invalid operand size for instruction | ||
| x072 | Not supported: <directive> | Message is displayed if one of the follwing options is specified: OPTION READONLY, OPTION EXPR16, OPTION OLDMACROS. Those are currently not supported. | |
| x073 | Size not specified, assuming: <type> | this is a warning. <type> may be BYTE, WORD or DWORD. The message may occur if an
immediate value is written to an untyped memory reference:

| x109 | Invalid command-line option: <option> | ||
| x110 | Internal error in <source file>(<line>) | This error shouldn't be seen in the release version. It's displayed if the internal assert() function is called, which usually is done when a "virtually impossible" error condition has occurred. | |
| x111 | Expecting closing square bracket | ||

| x150 | Missing operator in expression | ||
| x151 | Unexpected literal found in expression: %s | Literals enclosed in <> or {} are items processed by the preprocessor or to initialize "structured" data items. If they're used otherwise, this error will occur. | |

| x235 | Constant value too large: <value> | the value of the constant doesn't fit in 64 or - if it is a number to be assigned to a symbolic constant - 32 bits. | |
| x236 | Text macro was used before definition | this is a warning only. However, using text macros before they have been defined will force JWasm to do a full second pass, which increases assembly time. | |
| x237 | Offset size incompatible with current segment | ||
| x238 | Instruction form requires 80386 | ||
| x239 | Group/Segment offset size conflict: <group offset> - <segment offset> | Segments within a group must all have the same offset size. | |
| x240 | Assembly passes reached: <passes> | Although this is a warning only it usually indicates a severe problem. The assembler is very probably unable to calculate "final" values of all labels and has to be terminated by pressing Ctrl-C. | |
| x241 | Filename parameter must be enclosed in <> or quotes | The INCBIN directive requires delimiters for its filename. | |
| x242 | Start address on END directive ignored with .STARTUP | ||

| x247 | Type is wrong size for register | ||
| x248 | IF[n]DEF expects a plain symbol as argument | this is a warning. Masm accepts any expression as argument for directives [ELSE]IF[N]DEF, but the result probably isn't always what has been expected. | |
| x249 | Jump destination must specify a label | ||
| x250 | Ignored: <attribute> | An attribute or parameter of a directive was found, but not handled. See Known Bugs and missing Features for details about what features aren't implemented yet. | |
| x251 | Missing argument for cmdline option | ||
| x252 | Invalid coprocessor register | ||
| x253 | Registers AH-DH may not be used with SPL-DIL or R8-R15 | 64-bit only. | |
| x254 | .ENDPROLOG found before EH directives | 64-bit only. | |
| x255 | Missing FRAME in PROC, no unwind code will be generated | 64-bit only. | |
| x256 | Bad alignment for offset in unwind code | 64-bit only. | |
| x257 | Nonzero value expected | ||
| x258 | Size of prolog too big, must be < 256 bytes | 64-bit only. | |
| x259 | Missing .ENDPROLOG: %s | 64-bit only. | |
| x260 | .SAFESEH argument must be a PROC | ||
| x261 | Directive ignored without -%s switch | ||
| x262 | ELF GNU extensions (8/16-bit relocations) used | This is a warning only. The extensions are not "official", but the GNU linker LD will understand them. | |
| x263 | Syntax error in expression | ||
| x264 | Macro label not defined: %s | The target of a GOTO must be within the very same macro. | |
| x265 | Procedure argument or local not referenced: %s | This warning is displayed only if at least -W3 is specified. | |
| x266 | Group definition too large, truncated: <group_name> | The size of the OMF record that is to define a group would exceed 4 kB. However, to see this error you'll have to define a group that is to comprise more than 1000 segments, | |
| x267 | COMM variable exceeds 64K: <variable> | in 16-bit, the size of a COMM variable is restricted to 64 kB. | |
| x268 | Must be public or external: %s | Names that are to be known by the linker must be public or external. | |
| x269 | parameter/local name is reserved word: %s | This is a warning. The names of macro parameters or locals have highest priority and hence the reserved word will become inaccessible within the macro. | |
| x270 | real or BCD number not allowed | ||
| x271 | structure field expected | ||
| x272 | Constant value too large: <value> | the value of the constant doesn't fit in 64 or - if it is a number to be assigned to a symbolic constant - 32 bits. | |
| x273 | ELSE clause already occured in this IF block | An IF block may contain 0 or 1 ELSE clauses and it must be the last clause before ENDIF. | |
| x274 | Illegal use of segment register | ||
| x275 | Group exceeds 64K: <group> | MZ format only: a group that contains 16-bit segments cannot be larger than 64 kB, because the group must fit into a physical segment. | |
| x276 | EXPORT must be FAR: <symbol> | A 16-bit procedure that is to be exported must be declared with the FAR distance attribute. |
