In the table below are the additional constructs for Pascal-FC. They don't change anything to the functionality of the original compiler, just add some extra features, allowing for more expressivity.
|gotoxy(x, y: integer)||procedure||Allows positioning the cursor on the screen. X must be in the range of 1 to the screen width, Y from 1 to the screen height.||0.9.22|
|clrscr||procedure||Cleans the screen completely, and moves the cursor to the top left corner (x=1, y=1)||0.9.22|
Defines the color of the text to be printed next.
Valid colors are in the range of 0 to 15.
Defines the background of the text to be printed next.
Note: Valid colors are from 0 to 7. On some screens, values from 8 to 15 cause blinking.
|keypressed||function||Returns TRUE or FALSE depending on if a key was pressed.||0.9.27|
Returns the value of the pressed key.
Note: This function blocks if no called and no key is available!
