Section 5. Program Declarations

5-4

' Create the variable array A with 8 elements

Dim A( 8)

The maximum number of array dimensions allowed in a Dim statement is 3. If

a program uses a subscript that is greater than the dimensioned value, a

subscript out of bounds error is recorded.

When variables are initialized, they are set to 0.

Tip Put Dim statements at the beginning of the program.

PipelineMode

The PipelineMode instruction is used to configure the datalogger to perform all

instructions sequentially as they occur in the program.

Syntax

PipelineMode

Remarks

The datalogger has two processing modes: sequential mode and pipeline mode.

In sequential mode, instructions are executed by the datalogger sequentially as

they occur in the program. In pipeline mode, measurement tasks and

processing tasks are handled separately and executed concurrently.

The default mode of operation is pipeline mode. However, when the

datalogger program is compiled, the datalogger analyzes the program

instructions and automatically switches to sequential mode if the code requires

it. The datalogger can be forced to run in the pipeline or sequential mode by

placing the appropriate instruction at the beginning of the program before the

BeginProg instruction.

See OV2.3 for more description of the Pipeline and Sequential mode.

Public

Dimensions a variable as public and available in the Public table of the CR800.

Syntax

Public(list of [dimensioned] variables that make up the Public Table)

Remarks

More than one Public statement can be made.

Public Declaration Example

1 2 ... 109 110 111 112 113 114 115 116 117 118 119 ... 323 324
