What is the POKE command?

In computing, PEEK and POKE are commands used in some high-level programming languages for accessing the contents of a specific memory cell referenced by its memory address. PEEK gets the byte located at the specified memory address. POKE sets the memory byte at the specified address.

What is POKE in BASIC?

The BASIC command POKE changes the content of any address in the memory address, ranging from 0 to 65535, to the given byte value in the range 0 through 255. If either number is outside these limits, the 64 will display the error message? ILLEGAL QUANTITY ERROR IN line.

What programming language did Commodore 64 use?

In Commodore computers is CBM-BASIC using as OS and also as coding language: BASIC V2: C64 (all models), SX-64, VIC-20, PET. BASIC 3.5: C16, C116, Plus/4. BASIC 7.0: C128 (all models)

What are basic programming commands?

BASIC Commands

• Digital Input/Output.
• Analogue Input/Output.
• Time Delays.
• Program Flow Control.
• Interrupts and Multi-Tasking.
• Variables.
• Serial (RS232) Interfacing.
• Advanced I/O Interfacing.

Where can PEEK and POKE functions be used?

The most common uses of PEEK and POKE relate to early computing systems such as eight-bit processors. Here, the memory addresses were limited to a certain eight-bit (256-value) range. A user could issue a PEEK command to look at the contents of a particular memory cell.

How much is a Commodore 64 worth today?

Commodore Business Machines debuted its Commodore 64 back in 1982. It ended up being the best-selling computer in the company’s history. Today, one in mint condition could sell for nearly $1,200.

Can I learn to code?

Anyone can learn how to code, although don’t expect linear progress. Anyone can learn to code with persistence, the right teachers and optimal learning environment. While coding can be learned alone by sifting through dozens, if not hundreds, of tutorials, it will take significantly longer.

What is the most BASIC coding language?

JavaScript is the most common coding language in use today around the world. This is for a good reason: most web browsers utilize it and it’s one of the easiest languages to learn. JavaScript requires almost no prior coding knowledge — once you start learning, you can practice and play with it immediately.

What does peek () do in C?

The function peek() is used with input streams, and returns the next character in the stream or EOF if the end of file is read. peek() does not remove the character from the stream.

What is the most sold computer of all time?

What is x64sc?

The accurate C64 emulator, called `x64sc’ , features a cycle-based and pixel-accurate VIC-II emulation. This requires a much faster machine than the old `x64′ . A rather complete emulation of the SID sound chip is also provided.

What is vice c64sc?

VICE (Versatile Commodore Emulator) is an emulator for the Commodore 8-bit computer range. The Windows port of VICE is called WinVICE and emulates the C64, the C128, the VIC20, all PET models (except the SuperPET 9000), the PLUS4 and the CBM-II (aka C610).

Do coders make good money?

The national average for an entry-level coder is $53,000, but depending on your location you can earn an average of up to $80,000 a year. With more experience and a higher job title, the average salary drastically increases.

Does coding need math?

Since programming and coding require building logic around numbers, mathematics skills are essential for programmers to master. Without an understanding of certain concepts in mathematics, coders and programmers are left without the tools they need to succeed.

Why is C so hard?

It is hard to learn because: It has complex syntax to support versatility. It is a permissive language—you can do everything that’s technically possible, even if not logically right. It is best learned by someone who already has a foundation with C programming.

Was there ever a poke on a Commodore 64?

There’s little reason to mention this except word of the killer POKE was still circulating in the late 1980s, when the dominant Commodore computer was the C-64. It’s entirely possible that people tried it out on their 64s to prove it was an urban myth.

What happens if you write to ram on a Commodore 64?

On a Commodore 64, the command had no effect, since that address in memory was in the middle of a seldom-used block of RAM underneath the machine’s ROM. Since it was just RAM, writing to it did no harm.

What happens if you don’t have a poke on a C-64?

Caution: A misplaced POKE may cause the C-64 to lock up, or garble or delete the program currently in memory. To restore a locked-up C-64 without a reset button fitted, one has to momentarily turn off the power, thereby losing any program or data in RAM!
