clearfirst

Description

Clear field before input variable

Syntax

int clearfirst;

Remarks

The clearfirst variable governs whether a field is cleared before input is taken from the user. It can be set to 2 for entering new records and then reset to 0. Fields are only cleared if the corresponding field in the map also has the clearfirst property and the range variable indicates the field has not already been processed. The map_get_inputs() function will manage this variable for you so generally, there is no need to use this variable.
