Input of commands and statements

Commands and statements may be entered at the data display terminal either in guided or unguided dialog. To perform a given input it is possible to switch temporarily from unguided to guided dialog.
It is also possible to store the commands/statements in a file or a compound S variable for subsequent input by a procedure or in batch mode.

The command/statement input may contain expressions which SDF will replace by the contents of a job variable or S variable or, in procedures, by the value of a procedure parameter (see section “Replacing expressions in the input”).

Most of the information contained in this chapter can be displayed on the screen by means of the HELP-SDF command (see the “Commands“ manual [1]).
