I don't think -findname- has the ability to select on variable case (that I could find anyways ((I thought I remembered Nick Cox commenting about this in an earlier thread, but I couldnt find it - or I'm imagining it))) ).  

Here's a one way to do it:

*************!
sysuse auto, clear
rename mpg headroom, upper
**
foreach a in  `c(ALPHA)' {
cap ds `a'*
loc list `"`list' `r(varlist)' "'
}
di `"`list'"' //check this
drop `list' 
*************!

To clean the dataset I need to delete all variables that start with an upper case letter. I can see the names in ds or findname (from SSC) but I can't work out how to select these names for deletion. I would be grateful for any advice on this. I am using Stata 12.
