isSet(...)

The isSet(...) function can be used to check whether an object is available in the current context. This is useful if an object is context-dependent, e.g. the system object #cs .

The syntax of the isSet(...) function is as follows:

$CMS_IF(isSet(OBJECT))$
  VALUE
$CMS_END_IF$

The isSet(...) function can only be applied to an object and not to an expression.

Examples

Check whether the system object #cs is available:

$CMS_IF(isSet(#cs))$
  The system object #cs is available.
$CMS_ELSE$
  The system object #cs is not available.
$CMS_END_IF$

Check whether the variable sizeConstant is available in the context:

$CMS_IF(isSet(sizeConstant))$
  The Variable sizeConstant is available in the context.
$CMS_END_IF$
