while Command

while Basic Command

               while exp ... end

As a basic command, the while command provides repeated execution of embedded Jive commands (looping). while is followed by an expression that is converted to bool. While the result is true, the Jive commands that follow are executed up to an end. When the expression result is false, execution skips to the terminating end. For example,

while count '*' set count = count - 1 end

which outputs count asterisks.

while External Command

               {while exp} ... {end}

As an external command, the while command provides repeated inclusion of HTML text (looping). The while is preceded by a left brace ({). It is followed by an expression that is converted to bool. The expression must be followed by a right brace (}) to identify this as an external command. While the result of the expression is true, the HTML text (and embedded Jive code) that follows is included up to a {end}. When the expression result is false, execution skips to the terminating {end}. For example,

{while count}*{set count = count - 1}{end}

which outputs count asterisks.
