This configuration variable allows you to modify CALL, CHAIN, and CANCEL names at runtime. This can be particularly useful if you are using AcuServer or AcuConnect. When this variable is set to "1" (on, true, yes), every CALL, CHAIN, and CANCEL statement checks the current configuration for a name that matches the CALL name. This is handled in the same way that file name processing is done (the environment is checked for an uppercase version of the name, with any hyphens treated as underscores). If a matching name is found, its value is substituted. This is done recursively until no more matching names are found.
""After this substitution occurs, the CALL name handling proceeds normally (and includes any effects of CODE_PATH, CODE_SUFFIX, and CODE_CASE).
For example, if your configuration file had the following entry:
MYPROG @sun:/app/myprog
Then CALL "MYPROG" would act the same as CALL "@sun:/app/myprog".
The default value for this variable is "0" (off, false, no).
