There was a slight problem... incase the input was 'Nayeb' it shows the output 'NAyeb'... to solve the problem this is a slightly edited version. Thanks @Adam Danz & @Walter Roberson
S = 'NAyeb'
regexprep(lower(S), '[a-z]', '${upper($0)}', 'once' )
ans = 'Nayeb'

s = "99this"
s = "99this"
firstletter = letterBoundary("start")+lettersPattern(1)
firstletter = pattern
Matching: letterBoundary("start") + lettersPattern(1)
replace(s, firstletter, upper(extract(s, firstletter)))
ans = "99This"
