● No distinction is made between uppercase and lowercase type.

●

String variables are generally displayed left justified.

Strings can be deleted simply by assigning a blank string.

Strings can be appended after the equality sign using the operator "<<". Quotation marks (")

in the string are represented by two successive quotation mark symbols. Strings can be

checked for equality in IF instructions.

Example

Default settings for the following examples:

VAR1.VAL = "This is an"

VAR8.VAL = 4

VAR14.VAL = 15

VAR2.VAL = "Error"

$85001 = "This is an"

$85002 = "Alarm text"

Editing strings:

● Chaining of strings:

VAR12.VAL = VAR1 << " Error." ;Result: "This is an error"

● Deleting a variable:

VAR10.VAL = "" ;Result: Blank string

● Setting a variable with a text variable:

VAR11.VAL = VAR1.VAL ;Result: "This is an"

● Data type matching:

VAR13.VAL ="This is the " << (VAR14 - VAR8) << ". error"

;Result: "This is the 11th error"

● Treatment of numerical values:

VAR13.VAL = "Error" << VAR14.VAL << ": " << $85001 << $85002

;Result: "Error 15: "This is an alarm text"

IF VAR15 == "Error" ;Strings in IF statement

VAR16 = 18.1234

;Result: VAR16 equals 18.1234,

;if VAR15 equals "Error".

ENDIF

● Quotation marks within a string:

VAR2="Hello, this is a " Test""

;Result: Hello, this is a " Test"

● System or user-variable strings dependent on variable content:

VAR2.Var = "$R[" << VAR8 << "]" ;Result: $R[4]
