Not quite. From the JCL Reference: <quote> If your installation does not change the IBM-supplied default limits in the IEALIMIT or IEFUSI exit routine modules, then specifying various values for the region size has the following results: ... A value greater than 16,384K or 16M and less than or equal to 32,768K or 32M -- gives the job step all the storage available below 16 megabytes. The resulting size of the region below 16 megabytes depends on system options and what system software is installed. The extended region size is the default value of 32 megabytes. A value greater than 32,768K or 32M and less than or equal to 2,096,128K or 2047M -- gives the job step all the storage available below 16 megabytes. The resulting size of the region below 16 megabytes depends on system options and what system software is installed. The extended region size is the specified value. If the region size specified is not available above 16 megabytes, the job step receives whatever storage is available above 16 megabytes, up to the requested amount, and the resulting size of the region above 16 megabytes depends on system options and what system software is installed. </quote> -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
