Sadly, I found that it was out-of-date in some respects, and neither as explicit nor as well cross-referenced as it should be. That's now fixed in git (and the pages for "printf" and "eval" are also improved). Anyway, here's the executive summary: "print" is not designed to do what you want here; use eval or printf instead. The "print" command wants: * a list (named, or given in extenso) of one or more series, plus some options (its original and primary purpose); or * a single string literal; or * a space-separated list of names of non-series variables (scalars, strings, matrices, bundles, arrays). This command doesn't do any evaluation, including evaluation of members of bundles, or elements/ranges of matrices or arrays. One may perhaps wish this were otherwise, but it's the status quo (has been for some time) and it's now properly documented. Allin
