Re: Cobol in schools

Yes, it works, it is technically correct but why??????? ... There is absolutely no need for a conditional. ... the code should be written efficiently in the first place. If an unconditional jump (goto) is required then that is what should be used, if an unnecessary conditional is used then it shoul...

Re: migrating a VS program to RPI

If RPI is an SBC than shouldn't it compile in a time comparable to a PC? I don't follow the logic there. "SBC" is an acronym that has been in common use for many decades now and stands for "Single Board Computer". The is to say, an entire working computer on a single printed cir...

Re: What needs to programing java webservice ?

If you are talking about "web service" then that implies you are building a web server. Which implies you are using HTTP or preferably HTTPS. In which case I would suggest that you do not write your own HTTP/HTTPS server starting from sockets. That is tedious and error prone. It's not as s...

Re: Cobol in schools

One of the simplifications that came with structured programming is the notion of single-entry single-exit from each block of code. This is, in fact, what makes a block of code a block. Interesting. I do remember there was such "single-entry single-exit" rule back when structured programm...

Re: MSOffice on a Pi-400

Don't forget that the users on this forum are a tiny subset of total Pi users. It's a bit of an echo chamber, in that people most likely to post a lot on here are more likely to be anti-MS, so I don't think its a safe extrapolation to apply the same to the general Pi populace.

calculus is a standard term in dentistry.

It does have use in helping learn foreign languages. Often those Latin roots help things click together...
