SYS(30) Problem

[kgrix]

I've been writing code on a Unix Foxpro 2.6 platform for some 12 years and all of a sudden today I have two users that logged in as usual - when in the Foxpro command window, typing SYS(30) returns "root" as the login name of that user.

That scared the crap out of my boss and I don't have any idea what the problem is, or where to look.

Is it a Unix problem or a Foxpro problem ???

Please Help !!!

A quick Google search revealed at least a couple of things:

Sys(30) is a Unix command, not a FoxPro command

A substitute for sys(30) is getenv('LOGNAME')

I hope that helps!

I typed the command:
store getenv('LOGNAME') to m_login
and it did return the correct data (cs005).

I may just change my program to use that instead of the one I have been using for years:
store sys(30) to m_login

That is interesting, but let me make sure I am perfectly clear where I'm at.

After logging into Unix as "cs005" and checking my unix environment (env) - LOGNAME=cs005,

I then type foxpro -o -i -e -t to get to the Foxpro command window. From the Foxpro command window, I type the command ?sys(30) and it displays "root" on my screen. This has been working flawlessly for 10+ years - what could be going wrong all of a sudden.

I'm wondering if there is a problem and this is the first sign of it.

Since there is no Sys(30) in FoxPro, I can only guess that someone was feeling clever and wrote a sys() function to mimic the one in Unix. Something most of us know can easily come back and bite you.

I'm wondering if there is a problem and this is the first sign of it.

If my guess is correct, I would not be surprised.

Kgrix,
Do not know if SYS(0) will work in UNIX but you can try it.

cUserName=ALLTRIM(SUBSTR(SYS(0),AT("#",SYS(0))+1))

Have you upgraded your Unix operating system recently?

There is a documented issue with sys(30) & Red Hat.

Hey All,

Thanks for all your comments.

Cricket - we have upgraded our Unix operating system for the daylight savings change and since then, this problem has been occuring.

What I was wondering about was your comment about the documented issue with sys(30) & Red Hat. Where can I read up on that?
