SECTION 2. EDLOG
2.1 EDLOG INTRODUCTION
EDLOG creates, documents, and edits
datalogger programs. This version of EDLOG
has the following features:
Menu-Driven Format
EDLOG's menu-driven format is easy-to-use.
Section 2.2.1 lists and describes Edlog’s menu
(see Introduction I.5 for information on using the
menus).
Window Manipulation
Multiple EDLOG programs can be displayed
simultaneously. The size and location of each
program's window can be manipulated with the
computer's mouse or by using the Window
menu (see Sections 2.2 and 2.6). Sections of
one program can be copied and pasted into
another program (see Section 2.4.3.2).
Context-Sensitive Help
Context-sensitive help is automatically provided
at the bottom of the EDLOG screen. More
detailed help is also available by pressing the
F1 function key (see Introduction I.5 for more
information).
Labels Linked
After the user enters a new input location label,
EDLOG automatically assigns it the next
available input location number (address). By
using the Input Location Editor, all of the labels
can be entered first and the program written
later. The Input Location Editor also allows the
input locations to be edited (moved, inserted,
deleted); the input location numbers are
automatically changed wherever the labels
appear in the program. For more information
about input locations and the Input Location
Editor, see Section 2.5.
Compiler
After a program is written, it must be compiled.
The compiler checks program syntax and
attempts to discover programming errors. The
compiler also creates a .DLD file. The .DLD file
excludes all comments and incorporates the
instructions required to calculate the
expressions. The .DLD file is what actually
programs the datalogger. For more
information, see Section 2.8.2.
Trace Option
When the trace option is enabled and the
program is compiled, two files are generated.
One file displays program execution timing
information; the other lists final storage labels
(see Sections 2.8.3 and 2.8.4).
