Section 7. Creating and Editing Datalogger Programs

7.3.3.9.2 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 Constant 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)

Max=(value)
