The coding elements are arranged in groups of varying length (L) such that their combination provides ranges up to 224. Each group is symmetrical commencing and ending with the same element. The length (L) of each group and the hexadecimal range of the leading coding element defines the sub...
Normally, unescape processing is carried out for the values of symbols when they are put into the symbol table, so any characters specified using special coding are converted into the intended character. For example, plus signs are converted to spaces, and escape sequences are converted to the ...

Our ASCII table is structured with rows for each character and columns for decimal, octal, hexadecimal, binary, symbol, HTML number, HTML entities, and description, making it the most comprehensive and user-friendly resource available. Each row of our ASCII table displays a unique character or ...
We use the flexibility thatswitchoffers us and refer to the colors via our constants (COLOR_REDetc.) instead of hard-coding them ('Red'etc.). Interestingly, even though we do so, there can still be mix-ups. For example, someone may define a constant for a mood: ...
1. For the formula =SUMPRODUCT(B2,C2), we can add "$"& after the equal sign (=) of the formula, so the formula becomes: ="$"&SUMPRODUCT(B2,C2).2. Press ENTER to get the result.Now you can see a dollar sign is appearred before the formula's result. Then you can copy the ...
Behaviors are prewritten ActionScript scripts that let you add ActionScript coding to your document without having to create the ActionScript code yourself. Behaviors are not available for ActionScript 3.0. You can use behaviors with an instance to arrange it in the stacking order on a frame, as ...
This coding scheme allows a number of checks also. Four marks must be read for each carton or there is an error. Repeated sensing of the same mark does not cause problems since it has a unique subscript. Rotation of the carton around the cone axis does not cause problems. A convenient ...
