bash command operates differently with CALL SYSTEM

[Greynolds__Alan]

The following bash command line does what I want:

LCL_ALL=C tr ...

where the ellipsis is just some arguments and IO redirection stuff. However when I issue the exact same command line from my program (compiled with 11.1 on OSX 10.6):

call system("LCL_ALL=C tr ...")

it behaves as if the LCL_ALL=C is absent. Anyone know what's happening here?

your system call is creating a local environment (inheriting settings from your program runtime environment)
consider using EXPORT LCL_ALL=C tr...

I assume then I'll actually have to do somehting like:

call system("exportLCL_ALL=C && tr ...")

in order or execute the TRanslate command afterwards like my original syntax did.

Or invoke a shell script which sets the desired shell for itself.
