SYNONYM

api_par_nl()

SYNOPSIS

#include "dbapi.h"
 
long	_parnl(order [,index]))

DESCRIPTION

The _parnl() function returns a numeric parameter passed from Recital as a long. The order specifies the actual placement in the parameter list. If the parameter passed is an array, then the optional index value is used to specify the required element number.

EXAMPLE

The following example converts a Recital numeric value passed as the first parameter to a long.

Example Recital program:

m_long=1252
m_long=conlong(m_long)
return

Example 'C' function:

#include "dbapi.h"
 
dbapi_conlong()
{
    long	value;
 
    if ( _parinfo(1) == API_NTYPE ) {
       value = _parnl(1);
    }else {
       value = 0;
    }
 
    _retnl( value );
}
