KEYWORDS Almost every command that MPE/iX obeys contains KEYWORDS that the computer instantly recognizes. They always appear in CAPITAL LETTERS in the HELP dictionary entries. Keywords have to be spelled exactly as you see them, even if they look odd. variables In HELP, almost every command entry shows variables. You'll recognize variables in the HELP entries, because they appear in lowercase letters. Suppose you saw something like this: TIME = when. TIME is a KEYWORD here. It's always spelled t-i-m-e. In this example, "when" is a variable. TIME = 2:35 is acceptable. So is TIME = 10:02. And because MPE/iX uses a 24-hour clock, so is TIME = 22:19. But TIME = 44:26 pm is always wrong. There are lots of things you can choose to put in place of a variable in a command. One choice will work just right, while others won't work as well. And some won't work at all. So, what's the right one? It depends on what you need to do. HELP can guide you toward choosing variables and KEYWORDS that work with each command and the right punctuation. That's what we mean by SYNTAX. Back to Main Index
