As an SRE who is constantly fixing software bugs, adding features to open-source software, and writing scripts in various programming languages, I often wonder: At what point does my scripting work transform into full-blown programming work? What else is necessary to make the leap?
Empirically, at about 150 lines. That seems true for sh, PHP, Python and Perl.
Edit: somewhat fewer lines for Tcl/Tk for some reason.
Transcribing steps or developing/implementing steps?
Highly dependant on who you ask...
For some printing your first "Hello World" program qualifies you.. get that to be output on a webpage with a set of <h1> & <center> tags, you become full stack...
For other(s) though you could write an even more feature rich and faster version of ZFS filesystem, and they would still not consider you a programmer.
