As other suggested, COMPILE_OPT defint32 is the way to make the
default integer a long, but:

IDL> j = 0L
IDL> help, j * 100
<Expression> LONG = 0

IDL promotes the value of an expression to the type needed to hold the
precision all the operands. So here, because j is a long, the result
is a long.

As David suggested in the other thread, your issue here is probably
with graphics card memory.
