IDL> s = strjoin(['info', string(randomu(seed,10))], ' ')
IDL> vals = float((strsplit(s, ' *', /regex, /extract))[1:*])

For large files I sometimes read the whole thing into a bytarr and
split on line breaks
something like

openr, lun, 'big.txt',/get_lun
fs = fstat(lun)
buf = bytarr(fs.size)
readu, lun, buf
free_lun, lun
buf = strsplit(string(buf), string([13b,10b]),/extract) ; split on CR
+LF
