Appendix A.  Importing Short Cut Code 

Into CRBasic Editor 

Short Cut

 creates a .DEF file that contains wiring information and a program 

file that can be imported into the 

CRBasic Editor

. By default, these files reside 

in the C:\campbellsci\SCWin folder. 

Import 

Short Cut

 program file and wiring information into 

CRBasic Editor

1. Create the 

Short Cut

 program. After saving the 

Short Cut

 program, click

the 

Advanced

 tab then the 

CRBasic Editor

 button. A program file with a

generic name will open in CRBasic. Provide a meaningful name and save

the CRBasic program. This program can now be edited for additional

refinement.

Once the file is edited with 

CRBasic Editor

Short Cut

  can no 

longer be used to edit the program it created.  

2. To add the 

Short Cut

 wiring information into the new CRBasic program,

open the .DEF file located in the C:\campbellsci\SCWin folder, and copy

the wiring information, which is at the beginning of the .DEF file.

3. Go into the CRBasic program and paste the wiring information into it.

4. In the CRBasic program, highlight the wiring information, right-click, and

select 

Comment Block

. This adds an apostrophe (') to the beginning of

each of the highlighted lines, which instructs the data logger compiler to

ignore those lines when compiling. The 

Comment Block

 feature is

demonstrated at about 5:10 in the 

CRBasic | Features

 video  .
