        containFromRead = commaTextIo.read();


        while(containFromRead)
        {
            cols = conLen(containFromRead);
            for(x=1; x <= cols; x++)
            {
                info(any2str(conpeek(containFromRead, x)));
            }

CommaTextIO not initialized error

Query:

I am getting commatextio not initialized error and it is not going away. I am sure my code is right.

How can I pass information from 1 form to another?

Answer:
IN the clicked button of form A write following code,
void clicked()
{
    Args args;
    FormRun formRun;
    ;
    super();

    args = new Args(formstr(FormName));
    args.parm(parameters);
    formRun = classFactory.FormRunClass(args);
    formRun.init();
    formRun.run();
    formRun.wait();
    formRun.detach();
    parenttable_ds.refresh(); // Refreshing parent table DataSourceTable
    parenttable_ds.executeQuery(); // Refreshing Parent DataSourceTable Query
}

IN form B init method write following code

        hoursStr = substr(hoursStr, 0, decimalLocation);
        hoursStr = trimString(hoursStr, ["."]);
        minStr = num2str(hours, 0, 2, 1, 0);
        minStr = substr(minStr, decimalLocation, strlen(minStr) - strlen(hoursStr));
        minStr = trimString(minStr, ["."]);
        realPart = str2int(hoursStr);
        decimalPart = str2int(minStr);
        finalMinutes = hoursStr + ":" + (int2str(60 * decimalPart / 100) == "0" ? "00" : int2str(60 * decimalPart / 100));
