The separatorSymbol build descriptor option specifies a character used for separating the thousands and hundreds in a numeric value.
When you generate a COBOL program, if you do not specify the separatorSymbol build descriptor option, the value is set by the numeric separator character specified in the language-dependent options module specified for your runtime installation. For z/OS®, refer to the program directory for your runtime product for details.
When you generate Java™ code, the separatorSymbol build descriptor option assigns a character to the vgj.nls.number.separator Java runtime property, but only if the genProperties build descriptor option is set to GLOBAL or PROGRAM. If you do not specify the separatorSymbol build descriptor option, the default value is determined by the locale associated with the vgj.nls.code Java runtime property.
The separatorSymbol build descriptor option does not affect numbers in JSF Handlers. By default, JSF Handlers use the client's locale to determine the appropriate separator symbol. You can override the default locale with the sysLib.setLocale system function. You can find more information on this and other system functions in the EGL Language Reference.
