The backslash is needed in awk, as in the shell, when the line would be taken as a complete command if the backslash were not there.

As if (condition) is not complete, there is no need for a backslash.

__________________________________________________________________________________________________________________________________________________

NAME
Tcl_Backslash - parse a backslash sequence SYNOPSIS
#include <tcl.h> char Tcl_Backslash(src, countPtr) ARGUMENTS
char *src (in) Pointer to a string starting with a backslash. int *countPtr (out) If countPtr is not NULL, *countPtr gets filled in with number of characters in the backslash sequence, includ- ing the backslash character. _________________________________________________________________ DESCRIPTION
The use of Tcl_Backslash is deprecated in favor of Tcl_UtfBackslash. This is a utility procedure provided for backwards compatibility with non-internationalized Tcl extensions. It parses a backslash sequence and returns the low byte of the Unicode character corresponding to the sequence. Tcl_Backslash modifies *countPtr to contain the number of characters in the backslash sequence. See the Tcl manual entry for information on the valid backslash sequences. All of the sequences described in the Tcl manual entry are sup- ported by Tcl_Backslash. SEE ALSO
Tcl(n), Tcl_UtfBackslash(3) KEYWORDS
