NLUSERLANG and NLDATALANG values are retrieved by the subsystems through
calls to the NLGETLANG intrinsic. Application programs can also
use this intrinsic. NLGETLANG retrieves the value of the language
attribute requested and verifies its installation. If the value is
that of an unconfigured or undefined language, NLGETLANG returns a
language ID number of 0 (NATIVE-3000) and an error. To use either JCW, set the integer value corresponding to the language ID number desired, using the SETJCW command. The MPE XL Commands Reference Manual (32650-90003) lists the SETJCW command syntax.
