Re[2]: [amibroker] Re: STREXTRACT only works on comma separated lists??, AmiBroker Email List Archive

Ton, we all share that problem, but isn't this the case in all creative professions? I used to design electronic circuits and I would spend hundreds of hours reading and researching the best parts to use.

I use a brute force method and save everything I think I may ever need, this includes every revision of code I create (I scan my computer periodically), in an InfoSelect database. This is a massive collection of stuff (18000 items) that is bloated with duplication however it takes only a second or two to search and i don't have to go on-line. You can import the entire afl library, or download websites, so that they are included in your search. However I don't usually do this because I am more interested in small functions and programming tricks than full-fledged applications.

For quick reference I have an "AFL Building Blocks" folder in my Charts tree. This points to folders containing afl on selected topics. For example templates for starting new systems, sections that plot often used layouts, debugging routines, logging functions, etc.

This allows me to throw a system together in minutes. It frees time to explore new ideas and I don't get bugged down in mundane coding chores. Well, that 'mundane' part is actually not true ;-) functions get more complex and there are always better ways of doing things. I re-work code very often.

Herman that exactly is my problem. Theoretically you're absolutely right that we should first check the AFL Library that is available. But how do I find the function that I have in mind in a pool of 1000 AFLs ? That's my problem. In general it takes me more time to find what I need than to reinvent the function ... And here I am talking only about what is available in AFL. If you are adding TradeStation, MetaStock, Wealthlab code etc. etc. I am really don't know how to get what I want. So theoretically you're right but practically ... Perhaps we should develop a kind of expert base with all available functions that can find the requested function in a couple of seconds in stead of hours. Problem is that I have no idea how to get the thing doing what I want it to do ...

Regards, Ton.

Conrad,

congratulations with your decision. To get the biggest bang for your buck you should read through the entire afl function list once a day for two weeks. i am not kidding! Not only will you get the best value for your money you will also save yourself untold hours of programming functions that already exist. Why reinvent the wheel?

Str = StrReplace( Str, "|",",");

You can repeat this substitution as many times as you like to give you the format you want.
