In the description of append below, the six additions are
· wa to itab1
· initial line to itab1
· lines of itab2 to itab1
· from ndx1
· to ndx2
· sorted by f1.
In this reference manual, optional parameters are indicated by the square braces [ ] in the command description, and alternatives among those options are separated by the "pipe" or vertical bar |. If one of several parameters must be used, the list of parameters is enclosed in curly braces {}, and the parameters in the list are separated by vertical bars. Don’t type the braces or vertical bars in your programs.

Appendix A1 - System Fields
(by use)
SAP systems maintain a runtime array called
sy that contains a lot of data about the system and the program that’s running. You can get the values of these fields (and assign values to some of them) by referring to them as sy-xxxxx where XXXXX is the field name. For example the user’s login name is stored in SY-UNAME. Releases 2.x and 3.x have the same system fields. Releases 4.0 and 4.x each have slightly different lists of system fields. The fields in this list are valid for all releases through 4.6 unless otherwise identified. 78 of the original system fields are obsolete or for internal use only; those are not shown here.|

Notice
This edition does NOT include any Object ABAP information. An SAP reviewer pointed out that
some of the information is incomplete (e.g. MODULE), incorrect (e.g. TABLES) or obsolete (e.g.
OCCURS and ON CHANGE OF) for current (release 4.6) commands. That list of deficiencies is
probably not comprehensive. Dennis wrote the original book when the online help files were (to
be generous) were much less complete than today. He believes this book can still be useful to
ABAP programmers, but requests you check HELP when you're doing anything subtle.
If you send Dennis errors or shortcomings that you notice in the book he will add them to the list of corrections so everyone can benefit from your discoveries.
