while()

while

Evaluate a group of commands while a condition is true

while(condition)
  COMMAND1(ARGS ...)
  COMMAND2(ARGS ...)
  ...
endwhile(condition)

All commands between while and the matching endwhile() are recorded without being invoked. Once the endwhile() is evaluated, the recorded list of commands is invoked as long as the condition is true. The condition is evaluated using the same logic as the if() command.
