Extract upper case characters from a string
Hi Friends,

I have a script which returns me the following values line by line

ora_smon_RCAT102
oracleKHP102B (DESC
oraclePROOIDDB92 (DES
oraclePMS (DESCRIP
oracleBRIO (LOCAL=N
oracleBRIO (LOCAL=N
oraclePRDB92 (DES
oracleBRIO (LOCAL=N
oracleBRIO (LOCAL=N
oraclePMS (DESCRIP
oracleBRIO (LOCAL=N
oracleBRIO (LOCAL=N
oracleKHP102B (DESC

I need to extract from left all the letters which starts in upper case until it is the end of line or until it finds a space. Looking forward from the experts for a help.

Asad
