All variables are global in scope. That means that all variables to be used in the entire script must be

declared in the Variable Declaration section. All variables are visible from both the main program and

from user-defined procedures.

A variable is declared as

Where:

type = one of the data types in the following Data Types table

optional count = the way an array is declared. See the example below.

Example:

LampIntensity INT_16 declares a single integer while LampIntensity INT_16 40 declares

LampIntensity to be an array of 40 integers. Array indexing is inclusive [0...N-1] for a declaration of

VariableName Type N.

Scripting language is case-insensitive so that VariableOne, variableOne, and VARIABLEONE all

reference the same variable. Therefore, it is illegal to have a declaration section like the following:

VariableOne INT_16

VARIABLEONE INT_16 … error re-declaration or duplicate.

However, you can use any capitalization style you wish in your script since any sequence resolves to the

same variable.

Data Types

Type Name Contents Notes

INT_8 8-bit integer

INT_16 16-bit integer This is the preferred integer form

INT_32 32-bit integer

TEXT Null-terminated character

string

REAL Single-precision floating point

SPECTRAL Represents a spectrum

reading

FILE File of spectral data ASC = ascii

CSV = comma separated

RAW = tab delimited

TABLE 2-dimensional array of real

numbers

Meant to be used in computation with sample

spectrum

1 2 ... 7 8 9 10 11 12 13 14 15 16 17 ... 73 74
