FVSECT Prolog
NAME : FVS DESCRIPTION: Fixed Variable Storage Work Area DSECT : FVSECT FUNCTION : Workarea for file management routines; must also include the DMSAFT macro. FVSECT is used mainly by file management and I/O routines. FVS contains save areas, work areas, and commonly used constants. A typical use of FVS is when a reentrant I/O routine requires a work area or save area, because the routine cannot modify itself. FVSECT is called by the FVS macro.
