Here's what's in current git on the "newcomplex" branch. 1) As with other "genr" things, the current sample range is respected in creating or modifying series: we will not write outside of that range. 2) We have to able to match rows of the matrix to observations in the dataset. We do this by using the t1 and t2 tags attached to the matrix, if present (in which case it's an error if there's no overlap between the matrix t1 to t2 range and the current sample range). Otherwise we match if the number of rows equals the number of observations (a) in the dataset as a whole or (b) in the current sample range. Otherwise error. 3) We need valid series names. If the matrix has column names we use them. It's then an error if any of them are not valid identifiers, or if there are any duplicates among them. If the source matrix doesn't have column names we use the name of the matrix itself (if it's named), or failing that the name of the list to which the new series are being assigned. We append column numbers for uniqueness and it's an error if the matrix or list name is too long to accomodate the suffix. 4) If any of the names thus constructed are names of existing non-series objects, an error is flagged and no list is produced. If any of them are names of pre-existing series, the original series are over-written over the current sample range. Allin
