Hi,

I use also the Keil C51 compiler V5.02.
And I have never seen any difference in optimization on using the src statement or not.

Also its not more complicated to generate assembler first or the object directly.
Since I use a batch to make the whole job including download into the target.

At first all C51 files compiled, then all A51 files assembled and finally all OBJ files linked, which are found in the current project directory.
So it plays absolutely no role, if assembler generated in between or not. Maybe, the whole compiling job needs some milliseconds longer and some kB of harddisk space was needed more to hold the assembler file.

But no discomfort can be noticed at all.

P.S.:
I posted this magic batch already on this forum. If anybody was interest on it, please search or send me an E-Mail.
It runs also on a Windows-NT4 (service pack 6) in the DOS window.
