Introduction

A Value is the most basic of types within the project.
You can create a Value using the M-Value command, or as required, from within other objects.
There are a variety of Value types that are explored more below.

Notes:

• It is possible to utilise the Key of another Object as the value if the Type is suitable.
• It is also possible to select a Method which returns the same type as that required.

Option

An Option is a value limited to a range of values, available to that type.
An example are the Boolean values of True and False. The only possible values for that type.
Within a dialog box, an Option is specified by selecting one of the options from the drop-down list for the value.
The visible value is the current value.

Real

A Real value represents a real number to represent length arguments, etc..
There are Real Values and there are Real Objects, both of which return a value that can be used within other objects, such as a Point or a Vector to represent coordinates or distances.
Within a dialog box, there is a text field to enter the desired value.
Alternatively there are options on the RHS for additional ways to enter a value.

SZLPReal

A SZLPReal Object represents a Real number as an Object. And is passed and returned as an ID.

Subclasses of SZLPReal include means to create mathematical equations such as:

• +: Addition
  • SZLP-ADD to add two numbers and
  • SZLP-ADDS to add a list of values
• -: Subtraction
  • SZLP-SUB to add subtract numbers and
  • SZLP-SUBS to subtract a list of values
• *: Multiply
  • SZLP-MUL to muptiply two numbers and
  • SZLP-MULS to muptiply a list of values
• \/: Divide
  • SZLP-DIV to divide two numbers and
  • SZLP-DIVS to divide a list of values
