CONV

The CONV, or conversion, error condition may be specified at the end of a program statement, in the Exit statement and with the ON error statement.

Error Traps:

CONV traps the following four conversion errors: 1.) A numeric input field contains non-numeric characters or vice versa. 2.) The number is too big for the field. 3.) The I/O list item is numeric where the FORM format specification indicates a string, or visa-versa. 4.) A negative value is being input or output, but the PIC format specification does not specify a sign (negative symbol).
