"Break" statement can only be used in "For-Next",
"While-Wend", or "Select-Case" statements.
"Break" statement takes one line of Macro.
"Continue" statement can only be used in "For-Next"
or "While-Wend" statements.
"Continue" statement takes one line of Macro.
"xyz" represents an incompatible object.
The mismatch of operational objects in an
expression causes compile errors.
The format of function declaration is:
Sub(Macro_Command) [data type] function_name( )
End Sub(Macro_Command)
Formats other than this cause compile errors.
The number of parameters in a function's declaration
must be equivalent to the number of arguments
passed to the function.
Any variable or function should be declared before
use.
The parameter of GetData( ... ) , SetData( ... ) should
be legal PLC address.
The format of array is:
Declaration: array_name[constant]
(constant is the size of the array)
Usage: array_name[integer, character or constant]
Formats other than this cause compile errors.
Statement position of "int h , k"
declaration caused the error. All
declarations must be made before
operational statements.
The only one main entrance of Macro is:
Macro_Command function_name( )
End Macro_Command
You cannot nest or interleave Macro Functions.
