Administering and executing EDT procedures

The following statements are used to start EDT procedures and supply parameters to them. Further statements are used to switch between different procedure levels and to initialize and modify variables.

@DO (Format 1)	Starts a @DO procedure, i.e. the text lines and EDT statements in the specified work file are processed.	F mode L mode
@DO (Format 2)	Activates and deactivates the logging of the read statements (see the PRINT operand in format 1 of the @DO statement) at any location within the procedure.	@PROC
@END	In L mode, causes the current work file to be exited. Processing returns to the work file in which the @PROC statement activating the current work file was issued. In F mode, @END terminates the EDT session or terminates the screen dialog after @DIALOG.	F mode L mode
@INPUT (Format 1)	Starts an @INPUT procedure from any file. The statements and/or records in the file are processed sequentially.	F mode L mode
@INPUT (Format 2)	Starts an @INPUT procedure from a SAM or ISAM file. The statements and/or records in the file are processed sequentially. This format is now only supported for reasons of compatibility and should no longer be used.	F mode L mode
@NOTE	Does not perform any action. The statement is used to insert comments in EDT procedures.	L mode
@PARAMS	Defines symbolic parameters which can be used in a @DO procedure.	@PROC
@PROC (Format 1)	Switches to another work file. This work file then becomes the current work file.	L mode
@SET (Format 1)	Assigns a value to an integer variable.	F mode L mode
@SET (Format 2)	Assigns a value to a string variable.	F mode L mode
@SET (Format 4)	Inserts the contents of an integer variable, the name of a string variable or the contents of a line number variable as of a given column in printable form in a work file line or string variable.	F mode L mode
@SET (Format 5)	Stores the date and time as of the desired column in a string variable or a work file line.	F mode L mode
