1.6 Restrictions and Limitations

The following restrictions and limitations apply to the use of the multilingual support facilities:

• The multilingual facilities can only be activated in partitions that use the SAA/CUA standards option.
• When defining a new partition (or modifying an existing partition) to support multilingual applications a "default" language must be nominated.
• NChar and NVarChar fields are only supported on RDMLX objects in an RDMLX partition. They may not be displayed on *WEBEVENT functions.
• It is virtually impossible to fully develop a DBCS application on a machine that does not have a DBCS primary language and DBCS capable devices attached.
• For applications in bi-directional or DBCS languages you must use multilingual support, regardless of whether or not the resulting applications are truly multilingual (that is, able to operate in more than one language).
• The following table indicates dynamic language switching capabilities between the 3 main language groups:

  Compiled Language	LRTB	DBCS	RLTB
  LRTB	Yes	Yes *2*4	Yes *1
  DBCS *2	Yes *3	Yes	Yes *1*3
  RLTB	Yes *1	Yes *1*2*4	Yes

   |
   
       *1 indicates that some screen panels may appear strange in a dynamic switch between the languages. Recompilation would be recommended.
       *2 indicates that the machine must have IBM i or CPF DBCS support for the language being used as a primary or secondary language.
       *3 indicates that the display device should be DBCS capable or the operating system will issue an inquiry message indicating the device is non-DBCS. Recompilation is recommended if non-DBCS capable display devices are to be used.
       *4 indicates that recompilation is recommended if DBCS capable display devices are to be used.
