M4 also understands nested parentheses within a macro's argument list: Unbalanced parentheses can be quoted to protect them: In fact, quoting of the macro name is also recommended. The problem is that, within the second define, the macro LEFT was expanded before the define macro itself took effect: GNU m4 allows macros to have non-standard names, including punctuation characters like [.
In fact, the new macro doesn't seem to work either: We will see later how the ability to define macros with invalid names can be useful. Quoting the macro's arguments avoids this problem: How m4 works M4's behaviour can be mystifying. It is best to get an early understanding of how it works.
This should save you time figuring out what's going on when it doesn't do what you expect. First, m4 looks for tokens in its input — roughly speaking, it divides it into quoted strings, macro arguments, names i. Whitespace including newlinesnumbers and punctuation usually mark token boundaries; exceptions are when they appear within a quoted string or a macro argument.
The Version2 macro we have defined ignores its arguments -- but that doesn't matter to m4: In general, m4 passes input tokens and separators straight through to the output, making no change except to remove the quotes surrounding quoted string tokens.
When it encounters a macro name, however, it stops echoing to the output. An example makes this clearer: As the define macro expands to an empty string, nothing is output; however, the new macro num is now defined.
Then m4 reads in a space which it echoes to the output, followed by the macro num, which it replaces with its expansion.
Unless a nested macro is quoted, it is expanded immediately: Arbitrary nesting is possible -- with ordinarily an extra layer of protective quotes at each level of nesting: Clearly, plusplus doesn't work — it is read as a single token, plusplus, not two plus tokens: Thus, the next thing read in is the token plusoper.
As it doesn't correspond to a macro, it is copied straight to the output. The problem can be solved by adding an empty quote as a separator: Such an error is not always this obvious: Finally, look at this example: In this case the argument redefines the macro that's currently being expanded.
However, it is the expansion that was in force when the macro identifier was read in that is output. Similarly, it is possible to define a self-modifying macro or even a self-destructing macro: Sometimes you can just add an extra layer of quotes:In Word for Mac, you can create a macro that has a keyboard shortcut, run a macro, and delete a macro that you no longer need.

I'm trying to write a very basic macro in VB for Microsoft Word, but I don't have the required knowledge. I simply need to do two things: Insert a picture from file. WordStar is a word processor application that had a dominant market share during the early- to mids.
It was published by MicroPro International, and written for the CP/M operating system but later ported to feelthefish.comgh Seymour I.
Rubinstein was the principal owner of the company, Rob Barnaby was the sole author of the early versions of the program. Word works with Templates; it can’t do anything without Templates. Every Document has one, and Word, itself, has one. If you don't provide a Template it can use, Word will create one for you from a set of built-in defaults.
Dec 02, · (Or I write OK and three times Ctrl +->) Do I not need to do a loop? For that, you don't need either a macro or a loop. depending on what the macro does. A loop can't know that without being told. Word VBA doesn't have the concept "until EOF". You can read up on loops in beginner's books for VBA or research on the Internet.
The. A macro is a series of commands that is recorded so it can be played back, or executed, later. Creating and running macros isn't too difficult, and the resulting efficiency is well worth the time spent learning to use them. This tutorial covers macros in Word If you have a later version, you.
