Hi Keenan,

The scalcout record from the calc module

(https://github.com/epics-modules/calc) could theoretically do this by

using string replacements.

record("scalcout", "$(P)$(R)to_upper_1")
{
     field("CALC", "AA{'a','A'}{'b','B'}...")
}

Though, with a maximum length of 80 characters, you'd only be able to

get 8 replacements per record. You'd have to chain together a set of 4

of these records to make an entire string capitalized (and then another

4 records for lowercase).

  That is a pain which I love.

Another possible option is the luascript record from the lua module

(https://github.com/epics-modules/lua).

record("luascript", "$(P)$(R)to_upper")
{
     field("CODE", "return string.upper(AA)")
}

 From this, there is the more reason I have to study Lua record now.

It is the brilliant idea. Thank you again for guiding me to the new

adventure.

   Best,
   Han

P.S. I re-think the problem from scratch, and resolved it with the

different approach.

*Subject:* string conversion to uppercase or lowercase
Hi,

    Is there a way to convert a string from uppercase to lowercase or
vice-verse by using only available records within database files?

    Best,
