IHBADENV, EnvVarName must be a legal POSIX name, and the operation provoke no error from /bin/sh

InfoHub Error: This error occurs when configuration processing encounters an Env descriptor having EnvVarName that is not a legal POSIX name. This error also occurs when the shell reports an error when configuration processing passes each EnvVarName value to a shell invocation.

Action: Ensure that the EnvVarName is a legal POSIX name. A legal POSIX name consists solely of ASCII letters, digits, and underscores ("_"), of which the first character must not be a digit. If the error occurs from the shell, simulate the error condition in the shell environment and rectify the error.
