编程问题,已知答案和运算符号,如何获得运算数值?

dim a%,b%,c%
for a=1 to 9
for b=1 to 9
for c=1 to 9
if a +b+c=9 then
print a; b;c
next c
next b
next a
可以了

用循环语句一个一个的试。
dim a,b,c as long
a=0
b=0
c=0
do a>10 While
b=0
do b>10 while
c=0
do c>10 while
if a+b+c=9 then
print "a="& a &"b="& b "c="&c
end if
c=c+1
loop
b=b+1
loop
a=a+1
loop
