fast loading of variables from file (taken from old forum)

Post by MarioL »

HI,
in some programs it is necessary to load the values from a file and assign these to the variables in the shortest time,
this is likely the fastest method.
I used the command COMMAND temp$, temp $ is a string loaded from the file as "var1 = nnn : var2 = nn : ...... var$ = "pippo"

in alcuni programmi è necessario caricare i valori da un file ed assegnarli alle variabili nel minor tempo possibile,
questo, forse, è il metodo più veloce.
Ho usato il comando COMMAND temp$, temp$ e una stinga caricata dal file del tipo "var1 = nnn : var2 = nn : ...... var$ = "pippo"

Sorry, but does not look very attractive, (but instead, complicated).
No doubt because I'm not very familier with it.

MarioL's point is worth clarification - so In a nutshell...
Nearly all of his example is just lots of sample variables=data being saved to file as a single concatenated string$ using the : (colon) character.
So it serves only as lots of example data for demonstrating the point he is making.

His actual point is that multiple saved 'variable=value' pairs of data can be combined into a single string for sending to the COMMAND instruction to process with just a quick single command... instead of slowly reading in and processing every individual variable=data pair.
