9.3.9.2 Constant Customization
The Constant Customization feature allows you to define values for one or
more constants in a program prior to performing a conditional compile
(Compile | Conditional Compile and Save menu item). The constants can be
set up with an edit box, a spin box field for selecting/entering a value, or with a
list box. A step increase/decrease can be defined for the spin box, as well as
maximum and minimum values.
To set up Constant Customization, place the cursor on a blank line within the
CRBasic Editor and choose Tools | Set Up Constants Customization Section.
This will insert two comments into the program:
'Start of Constants Customization Section
'End of Constants Customization Section
Within these two comments, define the constants. Following each constant, use
the keywords noted below formatted as a comment, to set up edit boxes, spin
boxes, or list boxes for the constant values. The fields are edit boxes by default.
If a maximum/minimum are defined for a constant, the field will be a spin box.
If a discrete list is defined for the constant, the field will be a list box.
Constant Name=(value) Sets a default value for a constant
Min=(value) Sets a minimum value for a spin box control
Max=(value) Sets a maximum value for a spin box control
Inc=(value) The number of steps for a value each time the up
or down control on the spin box is selected
Value=(value) Defines a pick list value
