converting string to variable

[senweb]

dim a_1, a_2, a_3,i
a_1=x
a_2=y
a_3=z

for i=1 to 3
response.write( a_ & i)
next


result should be: xyz

But the expected result is not coming.
there is an error in response.write( )


pls. help me to solve it.

note: i want ASP coding

[code green]

Think it should be more like

response.write('a_' + i)

You cannot pass a name of a variable as string.
Why don't you use array:

dim a()
dim i
redim a(i)

a(0)=x
a(1)=y
a(2)=z

for c=0 to i
response.write( a(count))
next

[viktorka]

dim a()
dim i
i = 2
redim a(i)


a(0)=x
a(1)=y
a(2)=z

for c=0 to i
response.write( a(count))
next

[viktorka]

Sorry, another typo

dim a()
dim i
i = 2
redim a(i)


a(0)=x
a(1)=y
a(2)=z

for c=0 to i
response.write( a(c))
next

Viktorka's solution is the best, but this will also work (I use a similar approach for form inputs all the time):

session("a_1") = x
session("a_2") = y
session("a_3") = x

for x = 0 to 2
   response.write session("a_"+x)
next
