关于文本文件操作的麻烦问题，达人来帮帮忙！
以下是config.txt文本的内容，保存是一些参数！参数的行是不固定的（随机排列），如何将name后的参数修改后保存？

volume   "0.800000 "
suitvolume   "1.000000 "
hisound   "1.000000 "
bgmvolume   "1.000000 "
MP3Volume   "0.800000 "
_snd_mixahead   "0.1 "
name   "jordan "
team   " "
model   "gordon "
skin   " "
topcolor   "30 "
bottomcolor   "6 "
rate   "9999.000000 "
cl_updaterate   "20 "

[解决办法]
open app.path & "\config.txt " for input as #1
do while not eof(1)
line input #1,a
If Left(a, 4) = "name " Then
(name后的参数修改后保存)[lz这里的意思看不懂,呵呵]
end if
loop
close #1
