Output statement

Purpose: Output text.

@<text>

!<verbatim text>

Outputting free form text from Vely code is done by starting the line with "@" or "!". The text is output unencoded to the client with a new line appended.

With "@" statement, any inline-code executes and any output from those statements is output.

With "!" statement, all text is output verbatim, and any inline code is not executed. This is useful when the text printed out should not be checked for any inline-code (such as << ... >>).

All trailing whitespaces are trimmed from each source code line. If you need to write trailing whitespaces, with "@" statement you can use p-out as inline-code. Maximum line length is 8KB - this is the source code line length, the actual run-time output length is unlimited.

Note that all characters are output as they are written, including the escape character (\). If you wish to output characters requiring an escape character, such as new line and tab (as is done in C by using \n, \t etc.), use p-out as inline-code.
Examples
Outputting "Hello there" from Vely code:
@Hello there

You can use other Vely statements inlined and mixed with the text you are outputting:
char *weatherType="sunny";
@Today's weather is <<p-out weatherType>>

which would output
Today's weather is sunny

With "!" statement, the text is also output, and this example produces the same "Hello there" output as "@":
!Hello there

In contrast to "@" statement, "!" statement outputs all texts verbatim  and does not execute any inline code:
char *weatherType="sunny";
!Today's weather is <<p-out weatherType>>

which would output
Today's weather is <<p-out weatherType>>
