The self
directive is an obsolete directive that may be used for
conditionnal skipping of code. For a better approach see
Conditional directives.
The optionnal argument of +SELF
is If=
followed by
a conditionnal expression. If the conditionnal expression is true the
code following the directive is output, if it is false the code
is skipped up to any directive (including another +SELF
)
except +seq
.
