This study notes covers File Operations within File Handling for GCSE Computer Science. Revise File Handling in 3.2 Programming for GCSE Computer Science with 15 exam-style questions and 10 flashcards. This is a high-frequency topic, so it is worth revising until the explanation feels precise and repeatable. It is section 3 of 7 in this topic. Use this study notes to connect the idea to the wider topic before moving on to questions and flashcards.
File Operations
| Operation | GCSE Pseudocode | Purpose |
|---|---|---|
| Open for reading | myFile = open("file.txt") | Open file to read data |
| Open for writing | myFile = openWrite("file.txt") | Open file to write (overwrites) |
| Read line | line = myFile.readLine() | Read next line from file |
| Write line | myFile.writeLine("text") | Write a line to file |
| Close file | myFile.close() | Close file when done |
| End of file | myFile.endOfFile() | Check if at end of file |
Practice questions for File Handling
Which OCR pseudocode command is used to open a file called 'scores.txt' for reading?
Describe how OCR pseudocode reads all lines from a text file, using a WHILE loop. Include the role of endOfFile() in your answer.
Quick recall flashcards
How do you read a line?
line = myFile.readLine()
Why must you close files?
To save data and prevent corruption
