Special Characters

You can use these special characters in SYSTEM 2000 commands:

           $     _

     .     *     >

     <     )     ?

     (     ;     #

     +     ^     @

     |     -     '

     /     &     =

     !     %     "

Reserved Words and Characters

You cannot use these reserved words and characters in component names, even when they are preceded and followed by special characters. (For example, -OR- is not acceptable.)

In addition, you cannot use the following operator symbols in component names:

     =            <=                &

     >=           =<                |

     =>           ^>                ^

     ^<           !=                !

     !<

You can use the following words in component names, but you must reference the component in a command by its component number.

Restricted Usage To Begin a Component Name

     CNT
     OF
     RCNT
     RESUM

Restricted Usage Anywhere in a Component Name

     FOR
     THROUGH
     THRU

Reserved File Names

Following are the reserved file names:

     S2KSNAP      S2KSYS00       SF01

     S2KMSG       S2KSYS01       SF02

     S2KCOMP      S2KSYS02       SF03

     SYSUDUMP     S2KSYS03       SF04

     SYSABEND     S2KSYS04       SF05

     SYSOUT       S2KSYS05       SF06

     S2KUSERS     S2KSYS06

     TAPES2K      S2KSYS07       SF11

     KEEPFILE     S2KSYS08       SF12

     STEPLIB                     SF13

     SYSLIB       S2KSYS10       .

     S2KPARMS     S2KSYS11       .

     S2KPADnn     S2KSYS12       .

                  .              and so forth

                  .

                  .

                  and so forth

In addition, the following DDnames are reserved:

the eight DDnames used for the database files to be accessed in the same SYSTEM 2000 session
the two DDnames used for the Savefile and Keepfile.

A DDname consists of the first seven characters of the database name, plus a suffix. The suffix is a number from 1 through 8 for the database files, a letter S or K for the Savefile or Keepfile. If the database name is less than seven characters long, the DDname uses Xs to fill it out to seven characters. For example, if the database name is AUTO, the DDname for the Savefile is AUTOXXXS.

Collating Sequence and Character Set

The ascending collating sequence for the EBCDIC (Extended Binary Coded Decimal Interchange Code) character set is provided in this appendix.
