EXECUTION MODE
Live: will automatically execute upon every character typed (warning: could
result in issues if you have intensive or partially-completed code that results
in an infinite loop)
Exited code editor: will automatically execute code when the code editor loses
focus - i.e. when you click outside of the code editor
Run on click: code will only be executed when you click the triangular run/play
button

PROGRAMS
Choose from a number of pre-made programs or create your own
Modifying a pre-made program will automatically create a new program, ensuring
the original & modified version are available
AUTOFORMAT CODE
Toggle original/formatted code
Formatted code will insert new lines, indentation and apply consistent styling
rules
Note: you can even try writing your entire program on one line...and it should
still run and be formatted correctly :)
LOADING
Load a previously-saved pseudocode file (.pseudo default extension)
DOWNLOAD
Download a .pseudo file for future use
Note: programs will be saved periodically (every 10 seconds) to your browser's
storage if changes are made - this means you can access your programs across
multiple tabs
UPLOAD
Save your program for public-viewing by anyone
SHARING
Share a direct link containing your code - your code will be contained in the
URL and NOT stored on the server
Alternatively, you can select the upload option to upload your code publicly to
the server
FULLSCREEN
Toggle between regular and fullscreen mode
Note: pressing FN/F11/ESC keys isn't recommended, since they can't be detected
by us, hence we can't apply the desired styles. Hence why this toggle button
exists. Alternatively, CTRL + M (minimise <-> maximise) will also work

Checks
ERROR CHECKS
The site aims to enforce the statically-typed nature of pseudocode - i.e.
assigning a STRING to an INTEGER variable should be forbidden. Some combinations
are allowed, however - such as assigning a CHAR to a STRING or an INTEGER to a
REAL. Other additional checks to ensure valid pseudocode are also in place
The site has been well-tested and there aren't any bugs we are aware of,
however, if you believe the site is incorrectly giving you an error & preventing
your code from running, you can disable the error-checking
In such cases, please feel free to contact us
Note that it is not possible to disable fatal error messages such as syntax
errors, runtime errors etc
Hints
SUBROUTINE SIGNATURE HINTS
If enabled, the following information will be shown:
* Keyword/Identifier/Module Name Suggestions
* Subroutine parameters & types
* Return types
* Subroutine descriptions
* Examples
Font Size:
Max Execution Time:
MAX EXECUTION TIME
To prevent infinite loops resulting in the page becoming unresponsive, code will
automatically terminate if this value (in seconds) is exceeded
If you have a legitimate long-running program, you can obviously set this to a
high value - alternatively, setting to -1 will disable this check

WELCOME TO PSEUDOCODE PRO
This site was developed to solve the problems of students either being
completely stuck with pseudocode, or attempting a solution, but having no way of
actually validating if it would work (other than a manual trace table). This
site currently supports the entire Cambridge IGCSE (0478) and 9618 A-Level
pseudocode specifications from the guide/syllabus, with the exception of
pointers, which should be implemented in the future
Below are lists of both the currently support pseudocode and general website
features:
* 📦 Variables & Constants
* ➕ Arithmetic & Logical Operators
* 📥📤 INPUT & OUTPUT
* ❓❌ IF/ELSE & CASE
* 🔁 FOR/WHILE/REPEAT...UNTIL Loops
* 🔧 FUNCTIONS & PROCEDURES
* 🔢 BYVAL & BYREF
* 🔢 ARRAYs
* 📒 TYPEs (Records & Enums)
* 📄 File Handling (Text & RANDOM)
* 🧩 Object-Oriented Programming
* 🪣 Sets
* 🌟 Code-suggestions/auto-complete
* 🌈 Syntax Highlighting
* 🚩 Error messages & positions
* 💾 Loading/saving/sharing/uploading programs
* 🥇 Interesting practice activities of various difficulties (updated daily and
will have 500+ total)
* ✨ Pretty-printing
* ⌨️ Keyboard shortcuts
* 🎨 Changing appearance - font size, theme, layout etc
* 📺 Fullscreen & 📱 mobile support
64 demo programs from 14 categories are provided below for all of the pseudocode
features. You can click on them to load them into the editor, or simply use the
select box, arrow buttons or CTRL + LEFT/RIGHT arrow keyboard shortcut to change

While you are here, why not try one of the many - and ever increasing list of -
pseudocode coding challenges.
To support hosting & domain costs, for $2, a premium account can be purchased -
this has the following benefits:
* No ads
* A desktop version of the site which will load instantly & work offline
* Additional coding challenges (I will create 2 per day, will have 500 in total
eventually)
* License will be valid for Assembly Code Pro too
Those last 2 features are currently in progress, so an extra 3 months free will
be given to anyone who buys a license now to acknowledge this
For any issues, feature requests, comments etc, you can contact me
THANKS FOR USING THE SITE - I HOPE YOU ENJOY IT AND IF YOU DO, IT WOULD MEAN A
LOT IF YOU COULD SHARE IT WITH YOUR FRIENDS TOO :)
DRAG & DROP CODE OR DATA FILES HERE
🎉 WELCOME TO PSEUDOCODE.PRO
Important: removing ads & downloading the site as a desktop & mobile app now
available. Will make loading extremely fast and will work offline too. Directly
assigning arrays like a <-- [1,2,3], sets and try...catch exceptions are now
possible too. New features & improvements will be added weekly. Please let me
know if you have any questions, find any bugs or have any feature suggestions.

📚 Getting Started
Hopefully the site is fairly intuitive with simple 🟢 DEMO PROGRAMS 🟢 for each
feature
After choosing an option, you will also be able to see some instructions in the
output window
...but first, would you like to see the site's name in colour (y/n)?
💡[if choosing 'y' you will have to drag the output window wider to see it
properly]
