Constant to variable copy fault

[oliverb]

I haven't made a minimal code sample yet but if I declare a constant array containing 10 words and then write it to a variable then the generated code only copies the first 5 words of the array, basically it is copying the equivalent number of bytes.

Apologies for the messy code extract...

Code: Select all

const optiondefault as word[optioncount] =
    (0,0,0,50,1, 0,1,0,1,0)
dim optionvals as word[optioncount]



implements
dim aa,bb as byte
dim temp as byte
sub procedure default_config
  optionvals=optiondefault
end sub

Looking at the disassembly we find that only 10 bytes are copied not 10 words.

Code: Select all

Hi,
Could you, please, send me whole project folder to srdjan@mikroe.com.

I'll have to make up a code sample for you. The program in question has since been edited to use a for-next loop instead of relying on a whole-array assignment.

We are working on a new pro version of the compiler as we speak. This
bug is already solved there.
Thank you for reporting this bug.
