The ENVIRON statement is used to temporarily set or change an environmental string value.


ENVIRON stringExpression$


  • The stringExpression$ must include the environmental parameter ID and the setting:
    • Using an = sign: ENVIRON "parameterID=setting"
    • Using a space: ENVIRON "parameterID setting"
  • If the parameter ID did not previously exist in the environmental string table, it is appended to the end of the table.
  • If a parameter ID did exist, it is deleted and the new value is appended to end of the list.
  • Any changes made at runtime are discarded when your program ends.
