SBCS Machine to Create a DBCS Application

If your model is to be single byte, model value YIGCCNV is set to 0, the default condition; however, you may want to create an application for both single and double byte use. An SBCS system cannot create source, device files, or database files with IGCDTA parameters. This approach requires:

• Recreating these files on a DBCS machine with a parallel model.
• Ensuring that all device constants and input-capable fields to contain ideographic data are no less than four bytes long, the minimum requirement for a DBCS character.
• Ensuring that all text fields have the IGC field attribute which cannot be compiled on an SBCS machine.
• Externalization of messages is also recommended.
• Changing any data in lowercase English to upper case, using the following Toolkit commands:
  • YRTVMSGF—Retrieve Message File
  • YTRNPF—Translate Physical File Data
  • YTRNSRCF—Translate Source File Data
• Porting the model to a DBCS machine for compilation and execution.

Note: If you use the YCPYMDLOBJ command to copy from the source to another model, convert text fields needing the IGC attribute.
