About Debug in Harbour

[marcop...@gmail.com]

  Why, in Harbour, during debugging, does this small code snippet jump directly from the line if a = 1 to the line return, skipping the exit line when I step through the code using F8?

function main
clear
a = 1
altd()
do while .t.
   if a = 1
      exit
   endif
   a ++
enddo
return

Hi,

Harbour optimizes generated PCODE, removes dummy jumps,
joins others, etc. If you do not like then use -kj compile time switch.
If you want to see the difference in generated code then use -gc2
compiler switch and compare generated C files, i.e.:
    harbour -ks -gc2 tst.prg

best regards,
Przemek
