RE: st: set mem
I suspect this may be because one line of Fred's code has spilled over
two lines in his message. The following should all be on one line:
di in green "Maximum value of memory allowed by OS is " in
yellow"`memtest'm"
After setting up the command (the usual way would be to save it as
memtest.ado, although running it as a do file will make it work
temporarily), the command is just:
. memtest

Subject: 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
