question about comments in mql4/5 - page 2

Lorentzos Roussos:

declare the doubles outside the gates .you would get that issue with commenting out code too.

Thank you Lorentzos

I did.  I think filter/gates is not the best solution for what I am trying to do . Main reason if I put say 4 lines inside a gate they won't be accessible outside the gate when needed later , in the case above they will be needed. I think I am going to leave it as it is and not bother about loop producing only j+1 < or j+1+1<tfs results instead everything till j<tfs.

I get what you are saying about commenting . If i could comment out the 'offending ' lines I will comment out the block of lines where those variables appear(and are not needed) so not to have any errors.

Have you had any experience using conditional compilation ?

https://www.mql5.com/en/docs/basis/preprosessor/conditional_compilation

It would be interesting to find out how it is implemented . The mql4 documentaion does not have lot of examples.

thank you again

>>> conditional compilation

as it says, it compiles (read: composes, includes) parts of source codes during compilation time only.

After that, i.e. during runtime, the "not compiled/included code" are not available anymore, they are "excluded/thrown away".

*not sure if this is what  you need.
