Problem with 'AT' keyword

[arco]

If I define a structure and a character array at the same position:

Code: Select all

 Structure Blk
   Dim PPCheck        As Char[5]
       PPAmount       As Char[8]
       PPMin          As Char[5]
       VolSpkr        As Char[5]
       VolMicr        As Char[5]
       ConnectMax     As Char[5]
       HotDialDel     As Char[5]
       Provider       As Char[5]
       OutTime        As Char[5]
       InState        As Char[5]
       MeldTijd       As Char[5]
       OK             As Word
       HotdialNr      As Char[16]
       MeldNr         As Char[16]
       SMSNr          As Char[16]
       MenuPin        As Char[8]
       PPPrefix       As Char[8]
       Allowed        As Char[160]
       Contact        As Char[160]
       OutRepeat      As Char[5]
End Structure

Dim Parm              As Blk
Dim ParmBuff          As Char[580] At Parm

the program hangs directly after startup. If I omit the 'At Parm', everything is OK.
Why doesn't it work? I need to be able to address the memory area as separate parameters, and as a continous character array.
(this for writing the struct contents to flash)

If I check with statistics, they are neatly defined at the same memory location...

Hi,

Please attach the minimal project that represents this issue.

Interesting question. The examples only show the alias with ports and sbits. Does 'at' only work with simple types?

If you want a variable at the adress of another why not use the 'absolute' directive.
