Variable Services

  • Anthony S. Rudd

Abstract

The variable is the basic data item in the ISPF environment and consists of a name and value. There are two classes of variables: system and user. System variables are those variables defined by ISPF and concerned with its operational environment. System variables are themselves subdivided into two groups: modifiable and non-modifiable; all system variables have names which commence with “z” (e.g. ZDATE, ZUSER).
