create macro: Let's create a small handout with reports .
Posted: 02 May 2023 06:20
I'm going crazy creating macros and I ask you for help starting from simple examples.
If you have links that summarize I would like to know them.
I searched the forum and came across threads that always took for granted something that was too big for my mental capacity.
I need to optimize a script to run as fast as possible. A very good way is to create a code that creates other static code with calculations prepared beforehand.
But I still want to leave some calculations without necessarily pushing this method to the maximum. So I have code that needs to be executed differently depending on certain values.
Instead of using "IF" commands I wanted to create macros to insert into the code using the percent expansion "%" and the trick of eliminating the macro from the environment to perform "set" calculations as quickly as possible.
Request:
1) What changes do I need to make to achieve my goal?
2) for complex code should I use the LF trick? Can I avoid this by putting all the code on one line? What advantages are there?
3) what other precautions should I take into account to use both variables expanded by the "%" and delayed variables "!" at the time of execution of the macro?
4) Can I also use "%" and delayed expansions in the macro definition?
5) When executing the macro, can I use additional "%" and delayed "!" expansions?
This is the schematic of the code to transform/complete:
example of macro1:
or:
How should I define these macros?
EDIT: correct an error on code "else"
