It is not 'mad', but also not within the syntax of Rev.

In the case of a repeat loop the syntax for Rev is

REPEAT FOR EACH LINE varYouWantToUse IN containerOrVariable
REPEAT FOR EACH ITEM varYouWantToUse IN containerOrVariable
REPEAT FOR EACH CHAR varYouWantToUse IN containerOrVariable

so you cannot directly use
REPEAT FOR EACH chunkSynonym  IN containerOrVariable

Your " Repeat for each protein in allProteins" omits a key word

You could, of course, set up function or procedure handlers and globals, but
then you would be getting further away from English-like syntax.  The same
goes for the "do" command.

'make' is not a reserved word in Rev so you can use it to be a handler or
function

Hope this helps.
