-static const FX_WCHAR* const gs_lpStrErrorMsgInfo[] = {

[Tom Sepez, 2016/04/26 16:03:58]

Then this becomes

const FX_WCHAR kFMErrUnsupportedChar[] = L"unsupported char '%c'";

[dsinclair, 2016/04/26 16:36:46]

Done.

-    L"unsupported char '%c'",         L"bad suffix on number",
-    L"invalidate char '%c'",          L"expected identifier instead of '%s'",
-    L"expected '%s' instead of '%s'", L"expected 'endif' instead of '%s'",
-    L"unexpected expression '%s'",    L"expected operator '%s' instead of '%s'",
-    L"expected non-empty expression",
-};
-
-const FX_WCHAR* XFA_FM_ErrorMsg(XFA_FM_ERRMSG msg) {
-  if (msg < FMERR_MAXIMUM)
-    return gs_lpStrErrorMsgInfo[msg];
-  return L"";
