Assembler issue (error A152)

Pierre Roth

Hi,

I have included a file2.asm into a file1.asm using the following directive :
$INCLUDE(file2.asm)

When calling the A66 assembler on file1.asm, inclusion is well done but the following error appears :

C:\SourceCode\file2.asm(2): error A152: MPL FUNCTION 'THEN': '(' EXPECTED

I can't understand why... Here under the file2.asm content...

Any help would be highly appreciated !!

    Hi,

    TESTAREA is an MPL macro, you are right. What I have done then is to include everything needed into one single file but I can't still assemble it ! The assembler is not so verbose and I cannot understand my "syntax errors" even refering to the assembler doc and MPL macvro syntax.
    In fact, we were using Tasking EDE and we moved to Keil µVision3 and I am trying to port Memory test utility which can be found at www.tasking.com/.../AN019-12_v8.ZIP from tasking to keil : assembler should be the same but macros may differ... reading, comparing and reading again pdf's... Can't make this asm test memory compile :-(

    Thanks a lot for your time,

    Pierre

    PS : Note that MEM_TEST is defined from assembler command line.

    What makes you think that?

    Assembler syntax is not standardised!

    I know that assemblers syntaxes can be different but the assembly errors do not seem to be from assembly but from macros...

    Obviously macros are an integral part of assembly syntax. They're much less standardized than the machine language mnemonics themself, too.

    Macros are just about the last thing you should expect to be able to just copy and use from one assembler to the other

    1) save your stuff in a safe place
    2) copy the actual macro in place of the macro call
    3) assemble that
    4) this will give you line number in the macro
    5) the reason will bne obvious
    6) correct it - just to see
    7) restore what you put in a safe place
    8) correct the macro
    9) assemble with no error
    10) smile

    been there, done that
