syntax

<[ref]WHILE [NOT] conditional>
    block
<[ref]/WHILE>

synopsis

WHILE is the building block for repeated processing. The basic form is shown above.

"Conditional" is either a "compare" or "is defined" operation. A compare operator is a test of the value of a macro against a literal string. If the NOT tag is present in the WHILE markup, the evaluation of the conditional is reversed:

  <[ref]WHILE NOT i="10">
    ...
    <[ref]INC i>
  <[ref]/WHILE>

Just as with [ref]IF you can also check for a macro's existance:

  <[ref]WHILE sect-$i>
    ...
    <[ref]INC i>
  <[ref]/WHILE>

If the condition is true, the block is evaluated and afterwards the WHILE tag is evaluated again. If the '$'-operator is used in the WHILE tag it is also reevaluated on each iteration.

A loop block must be closed with the /WHILE tag.
