If you intend to use the prompt key in any non-SAA/CUA application, this area must contain a valid function key number in the range "01" to "24". For SAA/CUA applications the prompt function key number defined at the partition level is used instead of any value defined here.

External Security Matching. This is set to a "Y" to indicate that LANSA database security should be reflected into IBM i object level security. This option only applies to files set up and maintained by LANSA. It does not apply to "OTHER" files. Refer to the security references in Reviewing and Changing Access to LANSA Objects for more details of this option.

487

Y allows exchange list capability in RPG / CL / COBOL etc programs so that values can be returned from LANSA to these programs (using EXCHANGE).
Values can be put on the LANSA exchange list from RPG / CL / COBOL etc programs. Refer to the EXCHANGE command in the Technical Reference Guide for more details.
Recompilation is necessary for changes to this setting to take effect.

N is the default.

488

Decimal format for LANSA. This should relate to the IBM i system value QDECFMT. If QDECFMT = " " (blank) then the LANSA decimal format will = "." or If QDECFMT = "I" or "J" then the LANSA decimal format will = ",".

Values:

"."- LANSA decimal format is a full stop.

","- LANSA decimal format is a comma.

Other - LANSA decimal format is defaulted to a full stop.

WARNING: If the value of this field does not relate to the value of QDECFMT then UNPREDICTABLE results could occur with the use of numeric values.

495

Controls suppression of the "Process will run in interpretive mode, compiled version not usable" message. This message is displayed as a warning when a process has been selected for use, informing the user that a "new" compiled version of a Process should be created.

Values:

Y- do not display warning message.
N - display warning message is the default.

496

A

 

Indicates that end user process and function level security is disabled in this system. This setting will improve system performance, because no security checking is performed before accessing end user applications. This flag has no effect on access to process or function definition details in a development environment. This setting is appropriate for installations that use an external menu system to control and secure access to LANSA applications. Additional security checking within the LANSA application is a waste of resource and may mean "double updating" of end user access rights. The setting of this flag is interpreted dynamically by all applications that have been recompiled since the installation of program change 4.0/D3.

Values:

"Y"- process and function level security is disabled.

Other - process and function level security is enabled.

497

497

1

A

 

Indicates that end user file level security is disabled in this system. This setting will improve system performance, because no file level security checking is performed in end user applications. This flag has no effect on access to file definition details in a development environment. This setting is appropriate for installations that use the approach "if the program is accessible from your menu .... then you can access all the files the program requires". The setting of this flag is interpreted dynamically by all applications that have been recompiled since the installation of program change 4.0/D3.

Values:

"Y"- file level security is disabled.

Other - file level security is enabled.

498

A

 

Indicates whether a user defined prompt key message handler program should be called in preference to the LANSA prompt key message handler, when the prompt key function key has been selected. If this value has been set to "Y", a user defined prompt key message handler program name must be specified in the extended information data area DC@A07, please refer to the section on the 'extended information data area DC@A07' for more information.

Values:

"Y"- call user defined prompt key message handler program.

Other - call the LANSA prompt key message handler program.

EXCHANGE all fields from one function to another on a prompt request.

Values:
