Re: string conversion to uppercase or lowercase

["Lang, Keenan C. via Tech-talk" <tech-talk@aps.anl.gov>]

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).

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)")

}

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,
