_EDC_STOR_INITIAL_B

Sets the initial size of an internal library storage subpool acquired below the 16M line. The default below the line subpool storage size is 4K When _EDC_STOR_INITIAL_B is set, its value string is translated to the decimal integer equivalent. This integer is then used as the new setting of the above the line subpool storage initial size. The setting of this environment variable is only effective if it is done before the first I/O in the enclave.

Consider the case where setenv() is called from CEEBINT as follows, and with the CEEBINT user exit linked to the application.

   setenv("_EDC_STOR_INITIAL_B","1000",1);

Internally, the storage subpool acquired from 24-bit storage will be set to 4096 (that is, 4K). However, the subsequent call getenv("_EDC_STOR_INITIAL_B"); returns "1000", as set by the setenv() call.

Note: _EDC_STOR_INITIAL_B is not supported in AMODE 64. In AMODE 64, this environment variable is replaced by the IOHEAP64 runtime option.
