DIM'ming an array

[arco]

I have an array as buffer. I also want to split it into two for easy access.

Code: Select all

Dim DBuffer     As Char[1024]
    DBuffer_Lo  As Char[512] At DBuffer   
    DBuffer_Hi  As Char[512] At DBuffer[512]

For some reason the compiler acceps the DBuffer_Lo DIM, but not the DBuffer_Hi DIM [index]
Is there a workaround to do this?

Hi,

Unfortunately, you cannot use the keyword "at" in that way. After "at", the compiler expects the name of the variable, not the position in the array of chars, or the name of the register with access to individual bits in format (name).(bit number).

But you can do this in a few ways using pointers and strcpy function from String library.

With the use of "at" keyword:

Code: Select all

program test

dim DBuffer     as char[1024]
    DBuffer_Lo  as char[512] at DBuffer
    DBuffer_Hi  as ^char
main:
  DBuffer_Hi = @DBuffer + 512
  DBuffer_Lo = "TextLow"
  strcpy(DBuffer_Hi, "HighText")
end.

Without "at":

Code: Select all

program test

dim DBuffer as char[1024]
    ptr     as ^char

main:
 strcpy(DBuffer, "TextLow")
 ptr = @DBuffer + 512
 strcpy(ptr, "HighText")
end.

Kind regards,

Thanks,

That works...
