==Description==
The number of file control areas for <var class="product">Model 204</var> database files
One file control area is needed for each dataset of each <var class="product">Model 204</var> database file currently open during the run: DCBs in z/OS and z/VM, and DTFs in z/VSE.
Normally, file control areas are released when all concurrent users have closed the file. The X'10' bit of FRCVOPT causes <var class="product">Model 204</var> to retain shared control of the file even when the file has been used by all users. If a file manager sets that X'10' bit, NDCBS might need to be increased, because the file control area or areas used by the file are not released until the end of the job. If the file is reopened, no new file control areas are used. 
The value of NDCBS is increased automatically for CCAGRP and CCASYS. 
NDCBS can range from 1 to 32767 for z/OS and z/VM. For z/VSE, the maximum size you can specify depends on the label size of the operating system.
