Interpunction

How do ye do!

I am writing the text so as to ask you anent there is a conjugation 'comma-dash'. Virtually, it cannot be existed. Howsoever, dispite of this, I behold this punctuation mark, for example, in Shakespeare's books - as you like it, king lear, macbeth and the others - or various poems, for instance, a psalm of life - all this illustrate being of the mark ", - " which, in turn, demonstates something. Meseems, it shows an amplification as if we betake unto "do" or inversion. Somewhat another exemplar of the book "The military adventures" written by Charles O'Neil: "In one short half-hour the signal was to be given, - nay, even that little time was lost." (171 page). Also, ye shall contemplate this mark if ye shall open the book upon the 172 page. I know Shakespeare was inditing its poems with using the Middle English language. In that time Germanics bethought themself to create a system of punctuation marks so as to allow a reader heed of a sense, being in a text, more easily than it had been afore; in accordance with History the system was occurred, however, it was not stabilized, whenas it should have refined the system. Russians took the system to themself for the sake of enhancing their literature and amended in the systed with a goal of remaking this under themself is the Russian language. In English punctuation might have resembled with Middle Germanic. Notwithstanding this, English had been devoloping and has been doing this throughout all centuries. Rules de using ", - " in the Germanic language are tantamount unto Russian. Whereas in the Modern English language we do not use this. In lieu of this we write a simple dash or a comma, since it is the same; albeit, it depends on length pause: a comma has brief pause, whilst a dash vice versa has a long pause. Wherefore did Englishes eliminate the punctuation mark? Might have I made a mistake? Ergo I do speculate about this incorrectly. Or not? May it attests that the mark has another sense? I told the fact that the mark was using so as to make a sense more stronger unto my magister, giving her examples of deverse books, which has been mentioned above. Anyhow I crave to englighten myself and tell the truth to my teacher. What do ye think about this?
