jump is a macro which is defined to be the name of a register -- you can use register names as labels. Suggest you just delete lines 3 and 4.

lines 8 and 9 should appear after lines 10 and 11. The way they appear now lines 8 and 9 will always be executed regardless of the outcome of lines 10 and 11. Is that your intent? Probably not.

thank you for the responce sir, but the logic i meant was to increment r0 5 times using the loop delay , if you could send the corrected code, that'll be quite helpful..

Time to read the x86 assembler manual. You should be able to find a copy on the Intel web site...

Thanks this was an interesting bug fix discussion. It helped me fix my bugs as well.
