Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with ThinBasic.

What does this simple ThinBasic script do?
PRINT "Hello, World!"
SLEEP
This script prints the string 'Hello, World!' to the console and then pauses execution until the user presses a key.
What will be the output of this ThinBasic script?
DIM a AS LONG
a = 5
a = a * 2
PRINT a
SLEEP
This script declares a variable 'a' as a long integer, assigns it the value 5, multiplies it by 2, and then prints the result. The output will be '10'.
What does this ThinBasic script do with an array?
DIM arr(5) AS LONG
FOR i = 1 TO 5
  arr(i) = i * 2
NEXT
FOR i = 1 TO 5
  PRINT arr(i)
NEXT
SLEEP
This script declares an array 'arr' of long integers with 5 elements, assigns each element the value of its index multiplied by 2, and then prints each element. The output will be '2', '4', '6', '8', '10'.
What does this ThinBasic script do with threading?
USEUNIT TBGL
FUNCTION TBMAIN()
  TBGL_CreateWindowEx(640, 480, 32, TBGL_WS_WINDOWED)
  TBGL_NewList 1, %GL_COMPILE
  TBGL_BeginPoly %GL_QUADS
  TBGL_EndPoly
  TBGL_EndList
  DO
    TBGL_DrawList 1
    TBGL_PollMessages
  LOOP UNTIL TBGL_IsWindowClosed()
END FUNCTION
This script creates a window using the TBGL unit, compiles a new display list with ID 1, begins and ends a polygon definition, and then enters a loop where it draws the display list and polls for window messages until the window is closed.
