Re: [LINUX5250] Field mask

[MarkB@xxxxxxxxxx]

I don't want to speak on behalf of tn5250, but having written an emulator
of my own I may be able to shed some light on this topic.

Warning: The following is a bit of a guess.

Certain command or "Order" implementations are optional:
http://publib.boulder.ibm.com/cgi-bin/bookmgr/BOOKS/CO2E2001/15.6.3
I beleive it is a subcommand of the "Write To Display Structured Field
Order" which is responsible for setting up a field with field masks.

These commands are not required and a pain to implement. Therefore they are
missing from several emulators.

I have used some little tricks in my own emulator to avoid implementing
these commands.
One is, if there are any illegal characters in a field (such as '/' which
is illegal in a Numeric field), I just assume they must be
seperators/masks.

Just my two cents.

Which emulators do you have that it works in? Client Access and ___ ?

hi

I got this comment from a user of the ActiveX. Is this a generalized
problem? Or isn't it? I don't have access to an AS/400 so I can't reproduce
it.

There is a special field, sometimes referred to as a field mask.
It allows us for example to define an 8 digit date field and specify "/" as
a separator.  Both of our emulators support this by either showing the
separator and protecting it so the cursor just skips over it, or they leave
it blank but also skip over it.
