SYNOPSIS
#include "dbapi.h" int _parl(order [,index]) ) <input parameters> int order; /* Placement in actual parameter list */ int index; /* Array element index */ <output parameters> none
DESCRIPTION
The function converts a logical parameter passed from Recital to an integer, where .T. = 1 and .F. = 0. 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 Recital program:
m_condition=.t. m_word =ltow(m_condition) return
Example 'C' function:
#include "dbapi.h" dbapi_ltow() { char strbuff[6]; if ( _parinfo(1) == API_LTYPE ) { if ( _parl(1) == 0 ) { strcpy( strbuff, "False"); }else { strcpy( strbuff, "True"); } } else { strcby( strbuff, ""); } _retc( strbuff ); }
