Clanbs

clanbs allows you to know the number of variables used by a class.

Syntax

   clanbs(CLASS_DESCRIPTION,OPTION)
   clanbs(NUMERIC_EXPRESSION,OPTION)

• CLASS_DESCRIPTION is a class description with the [ABBR] syntax, where ABBR is the abbreviation of a class. Note, for classes of type file use [F:ABBR]
• OPTION is an integer expression returning 1 or 2.
• NUMERIC_EXPRESSION refers to the slot number for the class. This can be seen in the debugger, but should be considered internal.

Examples

  # Check the number of variables used by the local variable class
  NUMBER1=clanbs([L],1) : # The number of variables currently present in [L] variable class.
  NUMBER2=clanbs([L],2) : # The number of variables slots currently allocated for [L] variables

Description

clanbs allows you to return the number of variable slots used by a class available in the execution context (for example, table, local class, or global class). If the class is not available an errn=10 (type not compatible) is returned.

The second argument can either be 1 or 2:
* If 1, the number of variables currently used for variables in the class is returned.
* If 2, the size allocated to variable entries for the class is returned.

The result of the function is Integer.
