#EOF Built-In Function

Use #EOF to set a flag so that a process receives one end-of-file after it reads all the

data in a variable level. That variable level is one that is used either as the IN variable

of a #SERVER or as the DYNAMIC IN variable (see the #NEWPROCESS Built-In

Function on page 9-266) of an implicit server. If the variable level is not being used for

either of these purposes, #EOF does nothing. After a process has read the end-of-file

sent to it, the flag is cleared and subsequent read operations wait for more data or

another #EOF.

variable-level

is the name of a variable level used for DYNAMIC IN.

Result

#EOF returns nothing.

Consideration

Different processes handle end-of-file differently. For example, an EDIT process

started by the command

EDIT /INV in_var DYNAMIC/

stops as soon as it reads an end-of-file produced by

#EOF in_var
