Control Flow — bubblecode Docs

bubblecode provides English-like conditional and looping constructs that read almost like pseudocode.

If / else if / else

The basic conditional uses if ... then ... end if. You can chain conditions with else if.

example.bubble

put 85 into score
 
if score is greater than or equal to 90 then
say "Grade: A"
else if score is greater than or equal to 80 then
say "Grade: B"
else if score is greater than or equal to 70 then
say "Grade: C"
else
say "Grade: F"
end if

Comparison operators

Syntax	Meaning
`is equal to` / `is`	`==`
`is not equal to` / `is not`	`!=`
`is greater than`	`>`
`is less than`	`<`
`is greater than or equal to`	`>=`
`is less than or equal to`	`<=`

Repeat with (counting loop)

The repeat with loop iterates over a range of numbers.

example.bubble

repeat with i from 1 to 5
say "Step" && i
end repeat

Step size

Add by N to change the step size.

example.bubble

say "Counting by 5s:"
repeat with i from 0 to 25 by 5
say "  " & i
end repeat

Counting down

Use down to to iterate in reverse.

example.bubble

say "Countdown:"
repeat with i from 5 down to 1
say "  " & i & "..."
end repeat
say "  Blast off!"

Nested loops

Loops can be nested to any depth.

example.bubble

say "Multiplication table (1-5):"
repeat with row from 1 to 5
put "" into line
repeat with col from 1 to 5
  put padleft(text(row * col), 4) into cell
  put line & cell into line
end repeat
say line
end repeat
