Discuss PocketC for Palm OS (including Desktop Edition)

I'm trying to make some sense out of some code and I'm trying to figure out what "CHARS=(i/2)-1" means. Here's more of the code:
GetChar(){
int i=0;
int found=0;

dbopen(FILENAME);
dbrec(O);
while(found++0){
dbseek(i);
if((string)debread('c')=="0"){
CHARS=(i/2)-1;found=1;
}
i++;
}
dbclose();
}

Here's the situation:
a friend has given me his code and has given me permission to modify it (if I can figure it out:) ). I am brand new to this and am trying to figure it out. I'm really confused about why he would do "CHARS=(i/2)-1"
Would appreciate any insight or direction to where I could find some answers.
Thanks!

Since CHARS is not defined in this function, it must be a global. Search the rest of the code and see where CHARS is used to find out why it is needed.
