How to count upcase letter from a string in Base SAS?

[vishalrajpoot3]

From the below string how can I count the no of upcase letter?

data abc;
input name$30.;
datalines;
Name is Good
Name SHould Change
Name NOT Changed
;run;

1. Remove all lower case letters via REGEX or COMPRESS and count the length of the string
2. Convert it to all upper/lower case and see how many characters differ

3. Use COUNTC() with capitalized letters and the modifiers to avoid listing all letters - your best option

Typically when faced with a problem like this, I'll look through the SAS Functions by Category list and take a quick scan through all the character functions to see which ones could help me out.

Edited: to add countc() option.
