Selecting varlist based on value of variable in foreach loop

[Alexander Becker]

Hi,

I have to do a procedure for multiple subsets of data repeatedly. I defined three variable lists,

A_var B_var C_var

. Based on the value of my iterable, I then want to select the variable list.
However, I am struggling with implementing this.

foreach method in A B C {
  if `method' == A {
    vl create local_varlist = A_var
  }
  ...
  vl drop local_varlist
}

Some insights as to how this ought to work would be greatly appreciated!

Thanks,
Alex

I guess

 
 if `method' == A {

needs to be

  
 if "`method'" == "A" {

and in the rest of your code you need to distinguish (a) literal strings that are or are not variable names and (b) local macro names and their contents.

Awesome, thanks -- that did the trick! I suppose the intuition is that `method' is a string and thus the comparison needs to be between two strings, and as such, done explicitly.
