A sequence of QUERY commands can be named and stored in an MPE ASCII file, referred to as an XEQ file, for repeated use without re-entering the commands. The XEQ command is used to execute an XEQ file. For example, you execute an XEQ file named LISTNAME by typing:
An XEQ file must be created using EDITOR, TDP, or any editor which operates on ASCII files. You must exit QUERY to create an XEQ file.
The following is a list of differences between an XEQ file and a procedure:
Only one command can be stored in a procedure, while an XEQ file can contain a sequence of commands.
A procedure can be modified from within QUERY, while an XEQ file can only be modified using an editor outside of the QUERY subsystem.
An XEQ file is a unique file which can be listed using the MPE :LISTF command. However, a procedure is contained in a Proc-file and can only be listed within QUERY using the DISPLAY command.
The current Proc-file must be specified before a procedure can be executed, but an XEQ file can be executed at any time.
Refer to the XEQ command in Section 3 for more information on
using XEQ files.
