Iomode

Use Iomode to assign a value to the different parameters associated with a sequential file opened by Openi, Openio, or Openo when doing an abbreviation.

These parameter are adxium, adxifs, and adxirs.

Comments

When opening a file without an abbreviation, the setting of the parameters is done directly by assignment of adxifs, adxirs, and adxium. In this case, the use of Iomode is not necessary.
