What does "と" mean in "貴方を呼ばないと約束するから"?


I know "と" sometimes connects two sentences, implying consecutive actions,
reasoning or conditions. But none of these meanings fits here. My best guess
of its meaning is "I won't call you because I promised so."

But what does "と" actually imply here? What's the difference between:

[code]

    貴方を呼ばない約束するから
    貴方を呼ばないと約束するから
    
[/code]




と has a lot of uses.

As far as I know, と can be uses to point to:

  * a member of a complete list ( **X と Y と Z** => _noun X AND noun Y AND noun Z_ )
  * a cause of a natural consequence ( **condition A と natural consequence B** => _ALWAYS WHEN condition A THEN consequence B_ )
  * a partner also doing the action ( **person A と action Z** => _to do action Z TOGETHER WITH person A_ )
  * with certain type of adverbs (the so called **"adverbs taking the 'to' particle"** ), for example しっかり、だんだん etc.
  * a quote ( **X と [person A は] said** => _"X" said [person A_ ])

* * *

The と used here is a quotation particle:

`～と言う` => to say that ～

`～と約束する` => to promise that ～
