Hammer & Screwdriver Maybe this will assist you

I substituted the ~ for the first - and then my awk does formatted print to demonstrate that it sees two fields.

Code:
> cat file143
program 1 - program to do this
program 2 - program to do that - and the other
program 3 - program to do nothing
program 4 - program that wishes - it would do something
> sed 's/-/~/' file143 | awk -F"~" '{print "Program="$1"and info="$2}'
Program=program 1 and info= program to do this
Program=program 2 and info= program to do that - and the other
Program=program 3 and info= program to do nothing
Program=program 4 and info= program that wishes - it would do something

NAME
wcsncmp - compare two fixed-size wide-character strings SYNOPSIS
#include <wchar.h> int wcsncmp(const wchar_t *s1, const wchar_t *s2, size_t n); DESCRIPTION
The wcsncmp() function is the wide-character equivalent of the strncmp(3) function. It compares the wide-character string pointed to by s1 and the wide-character string pointed to by s2, but at most n wide characters from each string. In each string, the comparison extends only up to the first occurrence of a L'' character, if any. RETURN VALUE
The wcsncmp() function returns zero if the wide-character strings at s1 and s2, truncated to at most length n, are equal. It returns an integer greater than zero if at the first differing position i (i < n), the corresponding wide-character s1[i] is greater than s2[i]. It returns an integer less than zero if at the first differing position i (i < n), the corresponding wide-character s1[i] is less than s2[i]. CONFORMING TO
