Server Side Procedures - Parameter Passing Examples

Overview

For an overview of server side procedures, see here.

Lianja/VFP Server Side Procedures

exports.conf

A function can be called directly if it is declared in exports.conf.

var result = mylibproc();

Lianja.evaluate()

The Lianja.evaluate() method can be used to call a Lianja/VFP function/procedure.

var result = Lianja.evaluate("myproc()");

To call a procedure in a library, prefix the procedure name with the library name and '::'.

var result = Lianja.evaluate("mylib::mylibproc()");

Note how to build up the string passed to Lianja.evaluate() when using local variables:

Numeric variables:

var num5 = 5;
var num6 = 7;
var result = Lianja.evaluate("mylib::mylibproc(" + num5 + "," + num6 + ")");

String variables (include quotes):

var num7 = "5";
var num8 = "7";
var result = Lianja.evaluate("mylib::mylibproc('" + num7 + "','" + num8 + "')");

Macro substitution with {} can be used on globals:

Numeric:

num1 = 5;
num2 = 7;
var result = Lianja.evaluate("mylib::mylibproc({num1},{num2})");

Strings (include quotes):

num3 = "5";
num4 = "7";
var result = Lianja.evaluate("mylib::mylibproc('{num3}','{num4}')");
