Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

A period cannot be used in:
  ■ The name of a user-defined data type.
  ■ The name of an element in a user-defined type.
  ■ The name of a variable dimensioned as a
    user-defined data type.
 
Although variable names can contain periods, it is
recommended that a period be used only as a record variable
separator. If you have programs that use a period in
variable names, you could change them to use mixed-case
instead. For example, variable ALPHA.BETA would become
AlphaBeta.
