Title: Re: [amibroker] Re: Static Variables - Remove All
Graham,
There comes a time when using static variables becomes too unwieldy and one might want to consider other options. Using many static variables makes coding error prone... I can take a long time to find an erroneous var name.
You might want to look at the OSAKA table DLL, it has no size limit and you can delete the entire table with one single statement. Accessing this table is actually faster than using Static variables. You can reserve a table section for non-array static variables. While using OSAKA will take some getting used to (I had my share of problems) it offers some attractive options, like saving/recalling on/from disk (persistent behavior), sorting, csv format, easy deletion, and simulating arrays containing strings.
Using Composites is another option that may work at times. You can pack a fair number of ASCII characters in a single bar location using HLCVI spaces, but this gets slow. If your messages are always made up of the same vocabulary (Sell, Buy, Stop, etc.) you can also refer to pre-stored phrases by number, stored in a csv string, and save numbers the strextract the numbers in the price array. While this may work for simple requirements but it gets too complex for free use of text.
btw, I do not worry about removing a non-existent static variables. You can check for a NULL value but that will be slower than simply removing it.
best regards,
herman
