IBM OS/390 User Manual

POWER users specify the full eight-character FCB name, whereas OS/390 users
only specify the last four characters. POWER supports device-independent
specification of FCB-image phases in the * $$ LST statement by allowing 

″

$$$$

″

as the first four characters. POWER then replaces the dollar signs by a character
string depending on the printer:

 FCB1 For a 3800 printer
 FCB2 For a PRT1 printer (3211, 3203-5, 3289-4, 3262)
 FCB3 For a 3203-1 printer
 FCB4 For a 5203 printer
 FCB5 For a 4248 printer
 $$$$ For any other printer type

In OS/390, users specify the four-character name of the FCB and JES2 uses the
four-character prefix based on the device type. The FCB and UCS images are
stored in SYS1.IMAGELIB with device-dependent prefixes.

See 

DFSMSdfp Advanced Services, SC26-4921 and DFSMS/MVS Utilities,

SC26-4926 for OS/390 details.

In OS/390, Universal Character Set (UCS) images are stored in SYS1.IMAGELIB
with device-dependent prefixes. POWER does not have any particular naming
convention that must be followed.

JES2 supports four-character UCS names on JCL statements submitted by the
user. Depending on the printer device type, the following 

′

name is

prefixed to the name which is then retrieved from IMAGELIB:

•

1403 - UCS1xxxx

•

3203 - UCS2

•

3211 - UCS3

•

4245 - UCS5

•

4248 - UCS6

•

3262 - UCS6

The IBM 3800, when driven by JES2, uses character arrangement tables
beginning with XTB1.

For details, see 

DFSMS/MVS Utilities, SC26-4926, and DFSMSdfp Advanced

Services, SC26-4921

Both VSE/POWER and OS/390 JES2 support interactive user interfaces for job
submission and output retrieval, as well as other command functions. In addition,
many VSE/POWER installations use VM/CMS as their interactive terminal
system.
