2F. string ('bla')
Strings are any ascii representation, enclosed in single '' quotes.
The value of such a string is a pointer to the first character of it.
More specific: 'bla' yields a 32bit pointer to a memory area where
we find the bytes "b", "l" and "a". ALL strings in E are terminated
by a zero byte.
Strings may contain format signs introduced by a slash "\", either
to introduce characters to the string that are for some reason
not displayable, or for use with string formatting functions
like WriteF(), TextF() and StringF(), or kick2 Vprintf().

\n		a linefeed (ascii 10)
\a or ''	an apostrophe ' (the one used for enclosing the string)
\q		a doublequote: "
\e		escape (ascii 27)
\t		tab (ascii 9)
\\		a backslash
\0		a zero byte. Of rare use, as ALL strings are 0-terminated
\b		a carriage return (ascii 13)

Additionally, when used with formatting functions:

\d	print a decimal number
\h	print a hexadecimal
\s	print a string
\c	print a character
\z	set fill byte to '0' character
\l	format to left of field
\r	format to right of field (these last two act as toggles)

Field specifiers may follow the \d,\h and \s codes:

[x]	specify exact field width x
(x,y)	specify minimum x and maximum y (strings only)

Example: print a hexadecimal number with 8 positions and leading zeroes:

A string may be extended over several lines by trailing them with a "+"
sign and a <lf>:

'this specifically long string ' +
'is separated over two lines'
