Description
gcos_gein_pass1_ makes a pass over the deck to find cards, such as the EXECUTE card. It extracts the card type, and compares it to a table of lowercard card names. It is perfectly legitimate to use uppercase names for the cards, as shown in gcos_gein_, the main processor of gcos card decks, which *does* lowercase the card type before comparisons.
As a result, the first pass through the card deck doesn't find any EXECUTE cards, and consequently, sets switch 5 OFF. Any compilation activity leaves switch 5 off, and consequently, any EXECUTE activity is logically removed from the deck.
Changing gcos_gein_pass1_ to lowercase card types before comparing them causes the execution of compiled programs to work.
