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).
