MBCS_CHARSTRING_ Procedure

Summary

Parameters

Summary

The MBCS_CHARSTRING_ procedure tests the contents of a data string for the

exclusive use of MBCS characters of known internal character sets. This procedure

depends upon the MBCS_CHAR_ procedure to test each group of bytes in the data

string for validity; it inherently supports all the character sets known to the

MBCS_CHAR_ procedure. The MBCS_CHARSTRING_ procedure recognizes blank

MBCS characters. For the purposes of this procedure, a blank MBCS character is a

string of blank (%H20) bytes of the same storage length as an MBCS character of the

current MBCS.
