Re: st: set mem
I ran this ado file. Its still unclear how I could
obtain the information it should provide such as the
maximum allowable memory. After the do file, I tried
the following commands:
. memtest
Maximum value of memory allowed by OS is invalid
syntax
. memtest r(osmem_m)
Maximum value of memory allowed by OS is invalid
syntax
. memtest r(memory)
Maximum value of memory allowed by OS is invalid
syntax
