escape characters issue
Posted: 20 Oct 2018, 19:30
Generally it appears that text is read from left to right, and so:
``t is interpreted as `` then t and so appears literally as `t
``, is interpreted as `` then , and so appears literally as `,
However semicolon appears to be an exception:
``; appears literally as ;
I did not see any mention of this in the documentation. In case anyone can clarify the situation.
Here's an example of where having a good understanding of escape characters is important:
``t is interpreted as `` then t and so appears literally as `t
``, is interpreted as `` then , and so appears literally as `,
However semicolon appears to be an exception:
``; appears literally as ;
I did not see any mention of this in the documentation. In case anyone can clarify the situation.
