Welcome class! Today, we're diving into PFE, a specialized text editor designed for programming. Can anyone tell me what makes a text editor useful for coding?
Maybe features like syntax highlighting or auto-completing code?
Exactly! PFE makes coding simpler with such features. In addition, it offers direct access to DOS commands. Can anyone think of how that would help?
Oh, I think it would let you compile and run programs without leaving the editor.
Right on! PFE minimizes context-switching, keeping you focused. Remember, PFE stands for Programmer's File Editor, which emphasizes its purpose. What functions do you think it provides?
I read it can record macros. That sounds efficient!
Exactly! With macro recording, you can automate repetitive tasks. Let's summarize: PFE makes programming easier by integrating direct DOS access, macro recording, and supporting various programming languages.
Integration with SCILAB

Now that we've covered basic PFE functions, let's focus on how it integrates with SCILAB. Why do you think this integration matters?
It probably helps to keep scripts organized and easily editable.
Exactly! PFE allows you to edit SCILAB scripts and diary files efficiently. Can anyone explain how a diary file works in SCILAB?
It's used to keep track of commands and outputs during a SCILAB session, right?
Absolutely! When you run commands in SCILAB, you can save them into your diary file using PFE, making documentation easier. Letβs summarize: PFE enhances SCILAB usage by streamlining script and diary file management.
Working Directory Management

Let's discuss managing your working directory with SCILAB. Why is setting a specific directory important?
It keeps our files organized and ensures that we know where everything is.
Exactly! By default, SCILAB saves files in the current directory. You can check it using the command `pwd`. Does anyone remember how to change your current directory?
You would use the `chdir` command to navigate to your specified directory.
Correct! A common practice is to create a `work` folder for your SCILAB projects. This systematizes your work. To summarize, using a defined working directory enhances file management and clarity in your projects.
Introduction & Overview
Read a summary of the section's main ideas. Choose from Basic, Medium, or Detailed.
Quick Overview
Standard
PFE, a text editor for various programming languages, enhances the user experience for coding by providing direct access to DOS, macro recording, and easy navigation features. The section details its capabilities in managing SCILAB scripts and diary files, along with setting up and organizing the working directories.
Detailed
The PFE Software
PFE stands for Programmer's File Editor, which is a text editing tool that is particularly beneficial for programming in languages like FORTRAN, JAVA, and C++. This software is designed to facilitate direct access to DOS windows, enabling users to compile and test their programs easily. Furthermore, it allows users to execute DOS commands from within its interface, making it a seamless tool for managing programming tasks.
Key Functions of PFE:
- Macro Recording and Playback: PFE supports macro commands, making repetitive tasks more efficient by allowing users to automate common commands.
- Easy Navigation and Line Numbering: Allows for quick debugging by providing line numbers, helping programmers locate errors efficiently.
- Integration with SCILAB: PFE is particularly useful for editing SCILAB scripts and diary files, enhancing user productivity by managing code and documentation in one platform.
Setting Up Working Environment with PFE and SCILAB:
The section emphasizes the importance of a current directory where files are saved, especially while using functions like diary in SCILAB. Users are recommended to create a dedicated directory, usually named 'work', within the main SCILAB directory. The command pwd helps users check their current directory, and chdir is used to change their working directory to the desired folder.
Overall, PFE serves as a powerful ally for programmers using SCILAB, enhancing workflow efficiency.

PFE is a text editor designed for text-based programming in languages such as FORTRAN, JAVA, C++, etc. PFE allows the user direct access to DOS windows for compilation and testing of programs, runs DOS commands from the PFE interface, allows recording and playing of Macro commands, and permits easy navigation of files by allowing line numbering for easy debugging of programs.
Detailed Explanation
PFE stands for Programmer's File Editor. It is specifically built to help programmers write code in various programming languages without the complexity that some advanced IDEs possess. PFE helps you compile and test programs directly from its interface without needing to switch between different applications. This means you can write your code and immediately check if it works, which is a crucial part of programming. Additionally, PFE supports macro commands which are sequences of instructions that you can record and replay, saving time on repetitive tasks.
Examples & Analogies
Think of PFE like a multi-tool for a carpenter. Just like a carpenter can quickly shift between different tools like hammers, saws, and drills to accomplish various tasks, PFE gives programmers all they need in one place to write, test, and compile their code efficiently.
Using PFE with SCILAB

PFE can be used in combination with SCILAB to type scripts and function files or to edit diary files produced from within SCILAB.
Detailed Explanation
PFE is not only good for standalone programming but can also complement SCILAB, a computational software used for mathematical computations. By using PFE, you can write complicated SCILAB scripts or functions which can then be directly executed in SCILAB. This makes it convenient for users who want to combine the textual editing capabilities of PFE with the mathematical and graphical abilities of SCILAB.
Examples & Analogies
Imagine you are writing a book (the scripts/functions) using a good word processor (PFE), and the final book will be read and understood by an audience (SCILAB). Just as the word processor makes it easier to write and edit the book before it reaches the audience, PFE allows you to create complex mathematical scripts that SCILAB can then use to perform calculations.
Establishing a Working Environment

SCILAB uses a current directory where files are saved by default, for example when using the function diary. To see the current directory use: -->pwd. Under a Windows operating system, the default current directory is typically c:\. The command pwd stands for print working directory.
Detailed Explanation
In SCILAB, every time you want to save your work or load data, it needs to know where to look for these files. That βwhereβ is referred to as the 'current directory'. By using the command pwd, you can check what the current directory is. This is essential for file management. If you want to work on files that are not in the current directory, you need to change the directory using the command chdir to point to the right folder.
Examples & Analogies
Think of the current directory as your work desk. If your desk is cluttered with papers and tools from different projects, it can be hard to find what you need. By creating a specific folder for each project (like a clean desk for SCILAB), you can easily locate and work on your files without confusion.
Creating a Work Directory

I recommend that you create a sub-directory, or folder, called work and locate it under the SCILAB main directory. For example, under a Windows operating system, the SCILAB main directory will typically be c:\Program Files\SCILAB2.5. Thus, your work directory would correspond to: c:\Program Files\SCILAB2.5\work.
Detailed Explanation
Creating a dedicated 'work' folder helps organize your files related to SCILAB projects. By keeping all your scripts and functions in one place, youβll find that working in SCILAB becomes much more manageable. All files you create during each session can be easily accessed, leading to better productivity. To set this up you would normally use the chdir command so that SCILAB knows where to find these scripts.
Examples & Analogies
Think of it like setting up a specific drawer in your office just for SCILAB documents. This drawer helps separate your SCILAB files from other unrelated items, making it easier to find and work on your tasks without unnecessary distraction.
