mikoC PRO for PIC32
MikroElektronika
For example, the octal number \777 is larger than the maximum value allowed (\377) and will generate an error. The
rst nonoctal or nonhexadecimal character encountered in an octal or hexadecimal escape sequence marks the end
of the sequence.
Note: You must use the sequence \\ to represent an ASCII backslash, as used in operating system paths.
The following table shows the available escape sequences:
Sequence Value Char What it does?
\a
0x07 BEL Audible bell
\b
0x08 BS Backspace
\f
0x0C FF Formfeed
\n
0x0A LF Newline (Linefeed)
\r
0x0D CR Carriage Return
\t
0x09 HT Tab (horizontal)
\v
0x0B VT Vertical Tab
\\
0x5C \ Backslash
\’
0x27 ‘ Single quote (Apostrophe)
\”
0x22 “ Double quote
\?
0x3F ? Question mark
\O
any O = string of up to 3 octal digits
\xH
any H = string of hex digits
\XH
any H = string of hex digits
Disambiguation
Some ambiguous situations might arise when using escape sequences.
Here is an example:
Lcd_Out_Cp(“\x091.0 Intro”);
This is intended to be interpreted as \x09 and “1.0 Intro”. However, the mikroC PRO for PIC32 compiles it as the
hexadecimal number \x091 and literal string “.0 Intro”. To avoid such problems, we could rewrite the code in the
following way:
Lcd_Out_Cp(“\x09” “1.0 Intro”);
For more information on the previous line, refer to String Constants.
Ambiguities might also arise if an octal escape sequence is followed by a nonoctal digit. For example, the following
constant:
“\118”
would be interpreted as a two-character constant made up of the characters \11 and 8, because 8 is not a legal octal digit.
