Valery had created many groups in the Jive forum and one of them dealt with kind of a wish list. Things he would like to see in a better version of "Prime" which for some reason he called "Prime Minister". He posted a lot of messages there usually accompanied with a fake screenshot (edited, photmontage) to show and demonstrate what feature he would like to see.
As many other private groups this one seems to be not accessible - maybe its only accessible if you take membership there, I don't know. This forum sure has its act not together yet.
The screenshot he shows simply means that he would like that Prime would show ALL errors in an expression and not only the first one it encounters. If we enter an assignment and use a couple of undefined variables as Valery did, only the first one Prime encounters during parsing is flagged red and shown as error. If you correct it and define that variable, Prime would show the next, etc. Valery would like to see all of them flagged red in the first place as his screenshot implies.
I agree with Richard that Prime lacks of so many much more important features (we will probably never get) that it seems not worth the time to think about this one.
Valery seems not to be sure either as he created a discussion and not an idea.
BTW - have you noticed that we are not allowed to vote/kudo for Mathcad ideas? Honi soit qui mal y pense 😉 No, I really think thats just one unintentional misadjustment of the forum settings - not the most important one, as I consider those ideas a placebo which should keep us happy.
