Hi Nutsch,
macro substitucion means using the content of a variable as part of the code at execution time:
Example 1

a = "b"
&a = 10

suposing "&" sign is the macrosubstitution indicator.
Then at execution time &a will be replaced by the content of a
resulting in
b = 10 as the code executed.

Example 2
dim aa(2,2)
aa(1,1) = "w_cod"
aa(1,2) = "3543"
aa(2,1) = "w_nam"
aa(2,1) = "William"

for a = 1 to 2
  x = aa(a,1)
  &x = aa(a,2)
next a

Code executed in the loop will be
w_cod = "3543"
w_nam = "William"

Thanks !

From what I read here:


...the closest thing would be the String.Format method.
Instantiate a scripting.control object and put your 'macro' statements and use the results.  You can use the EVAL() function in this environment.

There is the possibility of creating a .Net program on-the-fly and have it compiled and executed.  I've never done this, but I think it is possible.
