RETURN command?

[Acetronics2]

Hi, Mike

I do not think I'ts a cultural practise, but an old time heritage ...

Have a look to the very first HP programmable calculators programming examples ( HP27C i.e. )
: the memory was very small and you had to spare as much space as you could to get a decent running program ...
If you deal with aerospace things, try to get infos about the processor used aboard the famous Grumman F14 ( called 944 ??? https://www.framboise314.fr/le-premi...u-f-14-tomcat/ ) ...


You are one of the " arduino generation " with plenty of wasted program space !!!
nowadays, we find processors with Huge memory and people do not care about wasting hundreds of addresses.

Now, in the end, I kind of feel you are confusing Basic subs and C functions ...

Try to think BASIC or C ... but do not mix them together !!!

I do not see any safety problem with multiple entries in a sub.

It is up to the programmer to write correct code and debug it. Say you want 5*6 and accidentally write 5**6. This is valid in PBP but whose fault is now. Compiler's?

Also valid is the conditional exit from a sub with many returns that depend on the conditions. Not efficient programming but for the sake of example:

mysub:
    if x=3 then
        y=4
        RETURN
    elseif x=5 then
        y=6
        RETURN
    endif
y=10
return

The main issue that SUB routines are just plain labels, there is no separate category like where you define that this code is SUBroutine, so for sure,there will be no conditional checks for matching number of gosub-returns.

[Ioannis]

Why this should be checked? I really do NOT want them to be checked so that I can conditionally choose where and when to exit the sub!

Hi Guys !

As I said previously, OK, everybody writes his own code as he likes.

It is not a matter of memory or old processors or any specific language.

It is a matter of writing a clean, easily understandable, easily readable code, which can be maintained by you of somebody else years after without too much pain.

End of the discussion for me. I have many projects to develop.
