IF never reached , whynot

[gharryh]

I have to decode a string from the serial input.
The input string looks likrnthis "99.0,99.0"
This is the sub:

void readData(char ch) {
  Serial << "Received: " << ch << endl;
  if (ch == ",") {
    Serial << "Calculate X" << endl;
  }
}

but the IF with the "," is never reached.
Any suggestions

if (ch == ",") {

Try

if (ch == ‘,’) {

snippets make things difficult to see what’s happening.

I'm finding it hard to follow the logical process that leads you to this conclusion
