Loops

Ooga Booga provides two loop constructs: UGGA WHILE for condition-driven loops, and UGGA DO for infinite loops. Both are closed with UGHA.

UGGA WHILE — while loop

Executes the body repeatedly as long as the condition is truthy.

OOGA i BE 0
UGGA WHILE i SMALLR 5
    SAY i
    i GETS i PLUS 1
UGHA

Output:

0
1
2
3
4

The condition is checked before each iteration. If it is falsy on the first check, the body never executes.

UGGA DO — infinite loop

Runs the body forever until a STOP statement is reached.

OOGA count BE 0
UGGA DO
    count GETS count PLUS 1
    IFF count IS 5
        STOP
    UGHA
UGHA
SAY count   OOF 5

Use UGGA DO when the exit condition is naturally in the middle or end of the body.

STOP — break

STOP immediately exits the innermost enclosing loop. Using STOP outside any loop is a semantic error.

OOGA i BE 0
UGGA WHILE YEAH
    IFF i IS 10
        STOP
    UGHA
    i GETS i PLUS 1
UGHA
SAY i   OOF 10

---

SKIP — continue

SKIP skips the rest of the current loop body and proceeds to the next iteration.

OOF Print only odd numbers 1–9
OOGA i BE 0
UGGA WHILE i SMALLR 10
    i GETS i PLUS 1
    IFF i MOD 2 IS 0
        SKIP
    UGHA
    SAY i
UGHA

Output:

1
3
5
7
9

Nested loops

Each loop has its own UGHA. STOP and SKIP only affect the innermost enclosing loop.

OOGA row BE 1
UGGA WHILE row SMALLR IS 3
    OOGA col BE 1
    UGGA WHILE col SMALLR IS 3
        SAY WORDY(row) PLUS "," PLUS WORDY(col)
        col GETS col PLUS 1
    UGHA
    row GETS row PLUS 1
UGHA

Output:

1,1
1,2
1,3
2,1
2,2
2,3
3,1
3,2
3,3

Tips

• Always update the loop variable inside the body or you will create an infinite loop.
• Use UGGA DO with STOP for loops where the exit condition depends on user input or complex mid-body logic.
• The Fibonacci example in the Examples page shows a practical while loop.
