CHANGE DATAPOOL TO A STANDARD COMMON BLOCK
[DO NOT] CHANGE DATAPOOL [ TO A STANDARD COMMON [ BLOCK ] ]
This command is used when migrating code from Gould-SEL MPX systems.
The Gould-SEL (Encore) DATAPOOL construct is replaced by a standard Fortran COMMON block named /DATAPOOL/. All variables in the DATAPOOL are declared in a single INCLUDE file which is inserted in every sub-program which needs it. Existing DATAPOOL declarations are removed. The addresses of objects in the DATAPOOL are preserved by writing EQUIVALENCE statements to a new byte array named DP_BYTE which forms a backbone to the /DATAPOOL/ COMMON block.
The command CHANGE DATAPOOL requires that a DATAPOOL listing file has been read. Please see the command DATAPOOL LISTING FILE.
