Multiple .tab files problem (AMQCHLTAB)

[Surcouf]

Hello,

My program is one of a few applications using MQSERIES on the same computer(Windows 95, soon to be XP). My problem is that my application needs a different config file(.tab) than the others.

Autoexec.bat contains
SET MQCHLTAB = AMQCLCHL.tab
SET MQCHLLIB = C:\MQCLIENT

After reading documentation i tried setting the environment variable MQCHLTAB to "abc.tab" in the application with no success. MQseries still try to access "AMQCLCHL.tab".
I move the variable setting to just before the call to MQCONN with no success.(I'm using Windows SetEnvironment variable)

So at this point my question is, how can i tell MQSERIES to use "abc.tab" with my application et use "AMQCLCHL.tab" with all the others applications?

Thanks id advance as i'm getting some pressure to make this work.
