Hi again,
Sorry, but my "minimal reproducible example" was apparently 
misleading. "value1" and "value2" are not fixed strings, but varying 
numbers. After a night's sleep I solved the problem using strsplit(), which 
gave me a big list of strings that I could process without wearing out the 
"\" key. Thanks for the suggestions.
