>>The following is not the correct translation from C. In C you have to substract the '0' char in order to have the numerical value of a digit character. In VFP you already applied the VAL function, which gives you the numerical value directly. So, the "- 48" substraction will give you a wrong value.

The message I replied to had HTML tags for preformated text. I inserted my reply between those tags, but I didn't format my text with CRs. Since it is between preformated tags, the browser takes it as is and doesn't format the text. So, the message is very wide.

Sorry! I will be more careful.
