7.3.4.5 Line Continuation

Line continuation allows an instruction or logical line to span one or more

physical lines. This allows you to break up long lines of code into more

readable “chunks”. Line continuation is indicated by one white space character

that immediately precedes a single underscore character as the last character of

a line of text. Following is an example of line continuation:

Public Temp, RH, WindSp, WindDir, _

BatteryV, IntRH, IntTemp, RainTot, _

RainInt, Solar

7.3.4.6 Inserting Comments Into Program

It is often useful to provide comments in your datalogger program so that when

you review the program at a later date, you will know what each section of

code does. Comments can be inserted into the program by preceding the text

with a single quote. When the program is compiled, the datalogger compiler

will ignore any text that is preceded by a single quote. A comment can be

placed at the beginning of a line or it can be placed after program code. If

Syntax Highlighting is enabled (Options | Editor Preferences | Syntax

Highlighting), commented text will appear formatted differently than other

lines of code.

'CR5000

'The following program is used to measure

'4 thermocouples

'VARIABLE DECLARATION

Dim TCTemp(4)

'Dimension TC measurement variable

Alias TCTemp(1)=EngineCoolantT

'Rename variables

Alias TCTemp(2)=BrakeFluidT

Alias TCTemp(3)=ManifoldT

Alias TCTemp(4)=CabinT

In the sample code above, the datalogger compiler will ignore the commented

text.
