SmallBasic starts by evaluating expression. If expression is nonzero (true), the next command is executed. If expression is zero (false), control passes to the first command following the next

WHILE. If that parameter is still nonzero (true), the process is repeated; otherwise, execution continues at the next command.
WHILE/WEND loops may be nested to any level of complexity, but there must be a WEND for each WHILE.
C=1 WHILE C<10 PRINT C C=C+1 WEND ... ' This is the same with that FOR C=1 TO 9 PRINT C NEXT
