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 

first 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:

\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.
