RE: HP 38G: Bug List Definitive (But Open for Additions)
So here is the complete list of bugs in the HP 38G:

1 Programme Editor

The top programme in the Programme Catalog is AA & a programme EDO appears lower down in the list of programmes.
You decide to make a new programme EDO in the New Program input form, which then asks "Replace existing program EDO?". On answering "YES" the text of AA appears. After deleting this text & entering the new programme, you will find EDO is now blank & AA contains the new programme.

2 Implcit Multiplication

The calculator enjoys the facility of implicit multiplication, eg KLM is accepted for K*L*M, 3M for 3*M.
Questionable behaviour occurs with SIN, interpreted as S*I*N & SIN(X), understood as sine function of X.
The bug appears on multiplying two conformable lists or matrices or complex numbers, eg M1*M2 is calculated correctly but M1M2 becomes M*1*M2, Z1Z2Z3 becomes Z*1*Z*2*Z3.

Of interest to followers of HP's history - These two bugs remain in the 40G & 40gs but NOT in the 39gii.
