There seems to be several ways to get a string of a symbol name (__VARINFO, {attribute 'instance-path'}, etc), but I can't seem to find a method of using a string of a symbol name to do anything. I'm specifically interested in using the string of a symbol name to get the address and size of the symbol. Is this possible in Codesys?
Currently, I sidestep this issue by manually generating code that returns the address and length of each item. However, my array of strings is automatically generated (so requiring zero effort/changes to use the code), so it would be nice to not need to manually alter this code to add ADR() and SIZEOF() calls.
