My goodness. You use an i for an inverted exclamation point and you are asking me to know what you mean. I wish! Look at Section 6.5 as mentioned for general information about the dash and what spacing to use. Also see 9.4 Blanks to be filled for using the the double dash in contact with a dash shown preceding conversation, which I think is the situation you have as you describe it. See Section 14.20 Spanish for details about the spacing of the inverted exclamation and question mark. The dot sequcne you give is not correct. All those 36's! There is no way for the reader to easily discern the conversatiion from the blank to be filled. The solution is in the sections given.
