I want to make it easy to write out my data to a file, using a macro
like:

 write_it(my_var)

which would envoke:

  #fopen myfile "abn.data" append
    #write(myfile,"my_var = ",my_var,"\n")
  #fclose myfile   

So my_var is output verbatim, then with its current value. How can I do
this?

The short answer ould be you can't.  The long answer would be to generate an
include file which does it for you.  That is, pass the variable name as
string.  Open an include file and write to it the three lines you quoted.
Then include that include file and it will output the variable for you.

There is Parse_String macro available in include files of official 3.5
distribution.
