I need one suggestions from you :-

Suppose I do have a code as below:

   until row == nil do      #code1      begin       #code2 <~~ which can raise an error      rescue      end      #here I want some guard which can check,if any error occurred or not.If #error then skip below part and continue from the next row.      #code3       row+=1    end

Just use error handling properly.

begin #standard code rescue #only runs if an error occurred else #only runs if an error did not occur ensure #always runs at the end regardless of error level end

It seems to me that OP may not even understand:

begin #standard code #only runs if no error earlier in this block rescue #only runs if an error occurred end #always runs as long as all exceptions are caught and none are re-thrown

I am looking for the below operations,but only when error will be occured :

a = (1..10) i=0 until a.size>10 next i+=1 if i<5 # this should be done on Error p a[i] i+=1 end

If still I am not clear,please let me know the confusions.

until val == nil   #line1   #line2 #<~~ error can be generated here.If error happened I want to start from #line1 again.skipping the below code.   #line3    ... end

Thanks

Maybe a real example would help, rather than infinite-loop pseudo-code.

val = -3 until val > 2   begin     val +=1     1/val   rescue     puts 'Error on ' + val.to_s   else     puts 'No Error on ' + val.to_s   end   puts 'Finished with ' + val.to_s end
