"split(s, a[,fs])
    Split the string s into array elements a [1], a [2], ... a [ n and return n . The separation will be done with the
extended regular expression fs or with the field separator FS if fs is not given. Each array element will have a string
value when created. If the string assigned to any array element, with any occurrence of the decimal-point character from
the current locale changed to a period character, would be considered a numeric string (see Expressions in awk ), the
array element will also have the numeric value of the numeric string . The effect of a null string as the value of fs is
unspecified. "

でも Solarist の /bin/awk が××なのは確か。
nawkはまともだけど。
