This is a pawn entity

Use strcat instead, https://sampwiki.blast.hk/wiki/Strcat

pawn Код:

strcat(pInfo[playerid][var1], "");

Or: (dont know if it works, just an idea)

pawn Код:

pInfo[playerid][var1][0] = EOF;
//or
pInfo[playerid][var1][1] = EOF;

If you got some time, feel free to test it, would be interesting to know if it works, as this would be much faster than strcat.
Basically, EOF is a symbol that tells pawn that the string is over here. Every string has this at the end, this is why
new txt[32];
could save a maximum of 31 chars.
