I’m not sure I understand your question 100%. You seem to be asking how to convert (the value of) a variable in a Windows batch file from mixed to all upper case. If so, the Super User question How to make uppercase all files and folder on a directory?, by seçkin bilgiç, contains an answer. Assuming that your variable is called obj (i.e., you have done set obj=Cockpit), do
setlocal enableDelayedExpansion ︙ for %%A in (A B C D E F G H I J K L M N O P Q R S T U V W X Y Z) do ( set "obj=!obj:%%A=%%A!" )
This uses the %variable:old=new% syntax for doing a substitution in a variable value. For example, if we do set animal=cow, then %animal:ow=at% yields cat. A useful feature of this is that the match for the old string is case-insensitive, but the replacement is case-preserving; so %animal:OW=AT% yields cAT. Similarly, if obj=Cockpit, then %obj:T=T% yields CockpiT, and so we can use this to replace a letter with the upper case version of itself.
We loop through the alphabet, getting the effect of
set "obj=%obj:A=A%" set "obj=%obj:B=B%" set "obj=%obj:C=C%" ︙
without having to do all 26 statements.
But variables behave strangely in loops in batch files. That’s why we have setlocal enableDelayedExpansion, and why we use !...! rather than %...% in the assignment in the loop.
