The videoform was written by Cao Changjiu himself, and all the advantages and disadvantages have already been made in his chest, and it is quite no suspense to make a spreadsheet software that surpasses it on the PC, and the difference is the workload.

The memory of the PC is only 16~32K, and the latest machine is 64K. Legend has it that the C code written by Da Neng can be comparable to assembly after compilation, and he has long thought that he has not reached this level, so for the sake of efficiency, he can only follow the example of Kapoor, the author of lotus1-2-3, and directly use the sink code (Lotus1-2-3 is what Kapoor and his accomplices spent ten months piling up with assembly).

The assembly didn't care for a long time, but without this time, the design of the microprocessor accounted for most of him, so he mobilized his software personnel to work on the project together.

Although vs-office has a little more things than Lotus1-2-3, it is better because there are more people, and there is a long-term expert to guide it, and ten months can be regarded as completion.

It's just that I hesitated a little in the development for a long time, and it was also a matter of hesitation memory. PC memory capacity 32k,That's fixed,At that time, there was no memory slot.,The memory is soldered one by one.,It's very difficult to expand.。 IBM's usual practice is to reserve a few empty soldering slots on the board, and if you want to expand the chips, you can solder them.

And to achieve a series of functions of VS-office smoothly, 32~64k is far from enough, this is the contradiction between hardware and software.

In this era, the usual practice is that software adapts to hardware, and what food is eaten is not allowed to be considered. However, after a little reference to some historical materials on the development of integrated circuits, especially memory, he resolutely decided to break through the 64K limit and directly let VS-Office support 256K memory.

Memory is an important indicator to verify the technology of integrated circuit manufacturers, and efforts to shorten the line width can obtain higher capacity and reduce costs, so it has always been a key point of contention.

Under the fierce competition, its production technology has been developing at the fastest speed for a long time, so Moore said a sentence: "Each new memory chip roughly contains twice the capacity of its predecessor, and each new memory chip is produced within 18~24 months after the previous chip is generated", which is the famous Moore's law, which was first used in the field of memory, and later expanded to all silicon chips.

It is with this understanding that I have dared to act like this for a long time, not to mention that now Japanese manufacturers are gradually emerging, and the price of memory is cheap and sufficient, so there is really no need to worry about the size of the memory. Therefore, the law of chip development cannot be desecrated, 64K will be eliminated soon, and all software that only supports 64K memory will eventually fail.

With the support of large memory, vs-office is like a fish in water, and its running state can be called smooth. I bargained for a long time, and when he used to write the videoform calculation table, he counted everything, and he could calculate fifty grids in ten seconds. And this time the design vs-office specially modified the rules, the program only counts those modified grids, so that the calculation process is accelerated in disguise, so that those large table users do not have to wait for the program to modify a table for a few minutes.

All these advantages reveal that VS-office is a software destined for success, and only a long time knows that there is a dead hole in it - assembly language.

In order to maximize the efficiency of the machine, to avoid the phenomenon of poor operation, for a long time is racking my brains, can think of all the ways I can think, and finally have to give up compatibility, the use of PC hardware features to improve performance, only support PC. Moreover, for the first time, assembly is not used in C, which also greatly reduces the portability of the software while improving operational efficiency.

There are gains and losses, and compromises on compatibility in exchange for excellent performance, and it is worth it for a long time, and then make up for these shortcomings after defeating other similar software.

The first mover always has an advantage, Microsoft is also famous, its programming language is still a must in the PC system, so people take it for granted that the Mutiplan spreadsheet released by Microsoft is not far behind, and the order is very strong, and the three-day conference sold 32 million US dollars. But there is also a weakness, that is, there are already computers on the market with 256k RAM, which Mutiplan does not support.

Zhang Yi was blessed by the big advertising a few days ago, and although VS-office was on the market at night, its popularity increased greatly. At that time, almost all people in the industry were stunned by Zhang Yi's advertising strategy, and the covers of all popular magazines and newspapers appeared in VS-office, this kind of bombardment of advertising was the result of Zhang Yi's discussion with Changjiu, and Changjiu was borrowed from Brother Zhuzi's brain XX marketing concept - direct advertising indoctrination method without foreplay.

It seems that the effect is not bad, and Brother Zhuzi's advertising bombing method also works well for foreigners, and people are not only interested in VS-office, but also interested in viewsoft.

The others were just interested, but Simeone was blue and bitter, he squeezed into the front row, saw the VS-office demo, and his heart was cold, and he understood that the good days of Mutiplan were over.

Simeone later recalled what he saw at the time, saying: "The first time I saw VS-Office, I knew that Mutiplan was out of play, and that's what I did. I jumped ship when I saw the popularity of videoform, and I thought I could do better, but when I did, the technology developed again. Of course, I only later learned that videoform and vs-office were originally written by the same person. ”

At that time, Simeone looked at the running screen of VS-office and vaguely felt that something was wrong, but he couldn't say what was wrong, so he had to pay for a set and go back to study.

After researching and researching, it suddenly dawned on me that VS-office is not only fully functional, but also supports 256K memory, which can process a large amount of data at a faster speed with the support of large memory.

This is too obvious compared with Microsoft's product one, mutiplan is too slow, which is of course very unpleasant for American business managers with a highly developed market economy and increasing business data, while VS-office can meet the requirements, as for the increased memory requirements are not a problem.

The Simeone report came out to the dismay of Microsoft, and the report showed that VS-Office uses a graphical method to store and display various data, and users can use it to draw various statistical or forecast charts they like, and draw two-dimensional coordinate axes.

This feature certainly also appeals to Americans who want to show off their individuality.

And because VS-Office also uses menus for human-computer dialogue, friendly interface, strong online help function, and provides users with an auxiliary learning program that can run independently under the godson system, it has attracted many buyers.

Microsoft, which has received a huge return, has not been happy for two days, and the sales performance of VS-office has surpassed Mutiplan, and its sales ratio is about three to one, that is, VS-Office bought three copies, and Mutiplan only sold one.

Bill was furious, but had no choice but to hold a meeting to discuss countermeasures.
