In addition to Neil's comments, 

1. There is no obvious gain from writing this as a program. 
You might as well just run these commands in a do-file. Of course, this may be under development. 

2. The line 

xtprobit expdum 'x', re

will not work as the same character ' is used for both delimiters. You need

xtprobit expdum `x', re

If you are going to write it as a program then you should save it as
[filename].ado (not [filename].do as you are implying) and place it in
one of your systems -adopath-'s (to see what these are simply type
-adopath- in Stata.

See [U] 16-18 for greater details on "Do-Files" (Chapter 16)
"Ado-Files (Chapter 17) and "Programming Stata (Chapter 18).
