How to update Array of String at specific location only once?

[omkargawde]

I want to update an array of string at specific location with a value from variable. But if the value of the variable changes again it should not affect the array updated.


I am attaching the following code for a better understanding of my need.




#platform "Gen4-uLCD-70DT"

#inherit "VisualConst.inc"

#inherit "DemoConst.inc"

func main()

var p, q;
var buff1[20];

var format;
format := "%*s\n%*s\n%*s\n%*s\n%*s";

//Create an Array of 5 and fill it with a string of Characters
var m[5];
m[0] := "Shiva";
m[1] := "Parvati";
m[2] := "Ganesha";
m[3] := "Kartikeya";
m[4] := "That which is not";

//Print that Array in the required format
p := str_Ptr(m);
str_Printf(&p, format);
putch('\n');
putch('\n');

gfx_Cls();

//Fill the Array buff1 with strings
to(buff1);
print("V");
p := str_Ptr(buff1);
str_Cat(p, "I");
str_Cat(p + 1, "S");
str_Cat(p + 2, "H");
str_Cat(p + 3, "N");
str_Cat(p + 4, "U");
str_Cat(p + 5, 0);
//Print that buff1
print([STR]buff1);
putch('\n');
putch('\n');

//Replace the m[2] with the buff1 filled above
q := str_Ptr(m);
str_PutWord(q + 4 , buff1);
//Print the m array. Note that the m[2] has been updated with buff1
str_Printf(&q, format);
print("\n");
print("\n");

//Update the value of buff1
to(buff1);
print("B");
p := str_Ptr(buff1);
str_Cat(p, "R");
str_Cat(p + 1, "A");
str_Cat(p + 2, "M");
str_Cat(p + 3, "H");
str_Cat(p + 4, "A");
str_Cat(p + 5, 0);

//Wait for 1 sec
pause(1000);

//Print the m buffer. Note that the value at m[2] has been updated
p := str_Ptr(m);
str_Printf(&p, format);

repeat
forever

endfunc


Note:
Array at m[2] was updated with buff1 and printed.
However, if buff1 is updated, the value at m[2] seems to update as well. I do not want this to happen.

Once the Array has been updated, it should be independent.

I do not know, if this is the appropriate method or not, however, I wish to carry out this task.

Can anyone help me with this? Thanks.

Hi,

Good day.

Welcome to the forum.

From your code, we can see that you are putting the address of buff1 to m[2]. Therefore, changing the value/string buff1 will also update the printed value.

You can try the attached project as a reference for your application.

I hope this helps.
