basic doubt

Hi ,

I got a basic doubt.When we compile and build our programs in keil simulator we are getting a line in the output window

Program Size: data=102 xdata=8184 const=45 code=7058

I would like to know what these numbers and the word data,xdata,const,code really denotes.

If I want to know my exact program size how can I know?

looking for your help

Hi,
This line brings out the total size of your code and variables used.

data : represents the total size consumed in the internal data memory. variables declared with the 'data' memory specifier are stored here.

xdata : represents the total size of local and global variables stored in the XRAM.

const: represents the constants stored in the code memory (in most cases)

code: represents your code size stored in the code memory.

The OP stated ARM, but omitted to state which compiler; the reply relates to C51.
