Re: [MI400] CVTCH run problem

["Leif Svalgaard" <leif@xxxxxxxx>]

Well, the CVTCH and CVTHC *are* confusing.
Have gotten me too quite a few times.
They should have been:
CVTCH : CVTHB convert hexadecimal character representation to binary
CVTHC: CVTBH convert binary to hexadecimal character representation.
so that
CVTCH (CVTHB)  BINCHAR, X'F1F2' ==> BINCHAR now contains X'F1F2'
CVTHC (CVTBH)  HEXCHAR, BINCHAR ===> HEXCHAR now contains C"F1F2"
