============================
函数名w_cut(type,num)
作用：字符串截取
参数type,num
type:字符串内容
num:字符串被截取的长度
=============================
Function w_cut(types,num)

for ci=1 to len(ctypes)
if cnum<0 then w_cut=w_cut&...:exit for

if int(asc(tt))>=0 then
w_cut=w_cut&tt
tc=tc+1:cc=cc+1
if tc=2 then
tc=0:cnum=cnum-1
end if
if cc>5 then cnum=cnum-1:cc=0
else
