EDT start procedure

The EDT start procedure is a special @INPUT procedure which is run when EDT is started (see section “Starting EDT”). The EDT start procedure is determined on the basis of the following search hierarchy.

1. If the link name $EDTPAR has been assigned then the file associated with it is defined as the EDT start procedure and the search is terminated.

2. If a file named EDTSTART exists under the caller of EDT's user ID then this is used and the search is terminated.

3. If in the EDT installation, the system administrator has assigned the logical identification SYSDAT.EDTSTART to an existing, accessible file then this file is used and the search is terminated.

4. If the file $.EDTSTART exists under the default user ID and is accessible then this is used and the search is terminated.

5. If steps 1 to 4 fail to identify any file then no EDT start procedure is executed.

Each time EDT is called, /SET-FILE-LINK can therefore be used to set an individual EDT start procedure. In particular
/SET-FILE-LINK FILE-NAME=*DUMMY,LINK-NAME=$EDTPAR

can be set to prevent the execution of any EDT start procedure including the one set by the system administrator.
