Often I have seen, that the requirement of SRAM was totally overrated.

I use always only the internal SRAM (128 byte on the AT89C2051 up to 8kB on the P89C668).

If you use a C compiler, it can very economical deal with the SRAM to overlay all the needed local variables (reading the C51 primer tell you why).

So the case can occur, that on programming in C less SRAM was needed as on programming in assembler.

Especially on bigger programs, the linker can do the job better than a human.
