CHECK-NUMBERS=value

Normally, ACUCOBOL-GT requires that numeric data be entered for numeric and numeric-edited fields that have the CONVERT phrase specified for them. If value is No, then any data can be entered and the runtime system will remove the non-numeric data from the user's input prior to converting. If value is set to Yes (the default), then a non-numeric entry will cause an error message to print and will force the user to re-enter the field. If value is set to Validate, the runtime system also checks to make sure that the numbers entered are valid, as described by the PICTURE clause for that field. The configuration variable KBD_CHECK_NUMBERS can also be used to set this value.
