Hi,

first of all apologies - 3 is obviously bullshit Smilie

Code:
vmo -p -o minperm%=3
vmo -p -o minfree=960
vmo -p -o maxfree=1088

Glad our suggestions did help Smilie

Regards

Agree with zxmaus : glad to see our suggestions helped!

By the way, you should (for example)
Code:
set lines 200
set pages 999

before generating spool : the output would be better formatted

Regarding the tip mentionned by zxmaus, you can a lot more by reading the whole chapter A of the link i have posted in #29
