Table D-1 contains the return value size generated by HP language compilers for each
data type. Use this information when you need to specify values with the Accelerator
ReturnValSize option. These tables are also useful if your programs use data from files
created by programs in another language, or your programs pass parameters to
programs written in callable languages.
Note that the return value sizes given in these tables do not correspond to the storage
size of SQL data types. For a complete list of SQL data type correspondence, see:
•
SQL/MP Programming Manual for C
•
SQL/MX Programming Manual for C and COBOL.
If you are using the Data Definition Language (DDL) utility to describe your files, see
the Data Definition Language (DDL) Reference Manual for more information.
Note. COBOL includes COBOL 74, COBOL85, and SCREEN COBOL unless otherwise noted.
