Question

Range arguments are partially back in Mathcad Prime 8 ..

Whilst playing around with some array extraction functions, I noticed that Mathcad Prime 8 partially restores Mathcad 15's ability to directly use ranges as function arguments.

    Here's vec modified to work in Mathcad Express 8 and operating over nested range arguments:

    I created an IsAtom function to determine whether an argument is a scalar, function or string and assumed that anything else potentially has multiple elements (ie, is an array or a range).  There have been several occasions when an IsRange function would have been nice.

     

    With my usual unbridled optimism, I hope the ability to use simple ranges as functions arguments is a foretaste of things to come - that is, fully stepped ranges and arbitrary sequences as arguments.   Indeed, I'd like to see proper, arbitrary sequences as a new data type.

    This is strange, I was just about to reply to a reply but the reply has disappeared (the original email is in my mail app, so I have good reason to suspect that I wasn't hallucinating).   I suspect it may have been regarded as spam.   However, it did link to a somewhat relevant Prime 3.1 thread where I noted the breaking of sequences in for loops: https://community.ptc.com/t5/PTC-Mathcad/Prime-3-1-Problem-with-until-function/m-p/402110/highlight/true#M157785

    Still broken in Prime 8 ...
