call - Execute object from a dictionary.Synopsis:
dict /f call -> -Description:
In SLI, an object-oriented programming style can beDiagnostics:
implemented by using dictionaries as objects.
These object dictionaries then contain functions as well as data.
The command call can be used to call a "member" of an object.
In calling the member-functions, the following steps are performed:
1. the object-dictionary is pushed on the dictionary stack
2. the name is executed in the new dictionary context
3. the object-dictionary is poped off the dictionary stack.
Thus, during the execution of the function, the entire namespace of the
object-dictionary is accessible.
The invocation of call is, thus, comparable but not equivalent
to the following sequence of SLI commands:
If the called member is not part of the object dictionary,References:
an UnknownMember error is raised.
