RE: [MI400] tags active/inactive?

[Gene_Gaunt@xxxxxxxxxxxxxxx]

I noticed "F10=Tags inactive" changes the 8-byte starting address input
field combination from a 10-and-6 nibble combination to a 9-and-7 nibble
combination.  Hmm, what does a 9-and-7 nibble combination, instead of a
10-and-6 nibble combination, signify for an 8-byte address, when tags are
inactive?

I noticed that trying to enter a perfectly valid 10-and-6 object header
address combination into these 9-and-7 input fields results in the error
line message, "80 exception, segment does not exist."

By the way, here is a way to change System Service Tools' "Display/Alter
Storage" so that lowercase letters appear in the "eyecatcher" right-hand
column area:

==> Start System Service Tools
==> 1. Start a service tool
==> 4. Display/Alter/Dump
==> 1. Display/Alter storage
==> 3. LIC module
==> 1. Find LIC module by name
==> enter module name:  S3FLAGS
==> press "F10=Display Data"
==> 1. Hexadecimal, alter capable

In other words, navigate to the data portion of SLIC module "S3FLAGS".

Counting the first data byte here as byte ONE, the fourth data byte
pertains to Display, and the fifth data byte pertains to Print.  Values for
Display and Print are:

x'01' = do not display lowercase letters
x'02' = fold lowercase letters into uppercase letters
x'03' = display lowercase letters

On my V4R5 machine, the S3FLAGS module's fourth and fifth data bytes were
x'01' and x'01'.  I changed them to x'03' and x'03', pressed "F11=Alter
storage", and wow, the "Display/Alter Storage" immediately started
displaying lowercase letters instead of periods in the "eyecatcher"
right-hand column area.
