  CDEC$ PSECT /common-name/ attr [,attr,...]

  The PSECT directive lets you modify several attributes of a common
  block.

  You specify the name of a common block, preceded and followed by a
  slash, and one of the following attributes:
    LCL         Local scope.
    GBL         Global scope.
    [NO]WRT     Writability or no-writability.
    [NO]SHR     Shareability or no-shareability.
    [NO]MULTILANGUAGE  Length padded to multiple of alignment or not
    ALIGN=val   Alignment for the common block.
                Val must be a constant (0 through 9).

  Refer to the "OpenVMS Linker Reference Manual" for detailed information
  about default attributes of common blocks.
