Example:
Precondition: There are two applications App1 and App2.
Variable "g_multitype" is declared in App1 with type LREAL
and in application App2 with type STRING:
{IF (hastype (variable: g_multitype, LREAL))}
(*the following code line will be processed only in App1*)
g_multitype := (0.9 + g_multitype) * 1.1;
{ELSIF (hastype (variable: g_multitype, STRING))}
(*the following code line will be processed only in App2*)
g_multitype := 'dies ist ein multitalent';
{END_IF}
