Below is UEFI definition for EFI_IFR_TYPE_VALUE, for string type, it use
EFI_STRING_ID to specify it, so for catenate, it uses STRING_TOKEN.
typedef union {
UINT8 u8;
UINT16 u16;
UINT32 u32;
UINT64 u64;
BOOLEAN b;
EFI_HII_TIME time;
EFI_HII_DATE date;
EFI_STRING_ID string; ///< EFI_IFR_TYPE_STRING, EFI_IFR_TYPE_ACTION
EFI_HII_REF ref; ///< EFI_IFR_TYPE_REF
// UINT8 buffer[]; ///< EFI_IFR_TYPE_BUFFER
} EFI_IFR_TYPE_VALUE;
Thanks,
Eric

Subject: [edk2] VFR Specification "catenate" example issue
The example for catenate (in 2.12.11.1) appears to be incorrect. I believe that
the parameters for catenate should be stringref(STRING_TOKEN), not just
STRING_TOKEN. Or at least the grammar doesn't seem to support a STRING_TOKEN in
vfrExpressionConstant and the current VfrCompiler.exe complains.
string varid = MyData.String,
prompt = STRING_TOKEN(STR_PROMPT),
help = STRING_TOKEN(STR_HELP),
minsize = 6,
maxsize = 40,
inconsistentif prompt = STRING_TOKEN(STR_CHECK),
pushthis != catenate (STRING_TOKEN(STR_STRING_RIGHT),
STRING_TOKEN(STR_STRING_LEFT)),
endif
endstring;
