Abstract

A variable declaration associates an identifier with a variable of that type. It consists of a list of identifiers denoting the variables, followed by their type and optional initialization. An initialization value must be type-compatible with the associated variable. The initialization is similar to an assignment statement executed immediately after the PLZ program is loaded into memory, except no program code is generated. This implies that, after execution, a program must either reinitialize its variables or be reloaded before being executed again. EXTERNAL and LOCAL variables cannot be initialized.
