Can someone throw some light on  the following for me.

We have a situation which involves three programs x, y, z.  The
important point seems to be that prog y is written in turbo Pascal (
I am not sure about the version but I think it is 5 or 6 ).  The
problem we have is as follows.

y     spawns      z                     OK
x     execs       z                     OK
x     execs       y                     OK
x     execs       y     spawns    z     Fails with insufficient RAM

The lanquage used for z seems irrelevant.
The lanquage for x is C.  We have tried MSC5.1 and 6 and TC 2 but
they all demonstrate the same problem.  When y is written in C there
isn't a problem.

What we are trying to do is that when a NEW version of some program
is installed on our file server, it gets put in a directory with a
'.NEW' extension.  The idea being that these are not in the PATH.  If
a user wishes to try the new version he types

    NEW    COMMAND    PARMS         instead of
    COMMAND     PARMS

This has worked well for ages.  We have found that it fails when the
program that is new is a TurboPascal program and it, as part of its
function, spawns other progs.

An explanation of this behaviour would be appreciated.  Our
experiments have indicated that when a Turbo Pascal program is
exec'ed it gets given all of RAM even though there is a compiler
directive that told it to only allocate a small heap :-(
