[mwebb at linux ~]$ cat m
linewithnospaces
a space tab/slash:colon

       ^___ tab

[mwebb at linux ~]$ cat p.awk 
#
#
BEGIN   { FS="[ \t/]" }

        { print "[", $1, "] [", $2, "] [", $3, "] [", $4, "]" }

END     { }

[mwebb at linux ~]$ awk -f p.awk m
[ linewithnospaces ] [  ] [  ] [  ]
[ a ] [ space ] [ tab ] [ slash:colon ]

Easier than perl...
