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.

Associated errors

Error	Description
10	Type incompatibility
50	The numeric argument is negative.
