HP41C - workaround for the SIZE? missing

[RMollov]

Some 30+ years ago, a structural engineer I worked for had a 41cv program to calculate if pile depth is enough to support future structure or something; I only did surveying work for him. The program used to run for more than 5 hours, sometimes 6 or 7. We used to sit in the pub nearby watching the flying goose while sipping gin and tonic and other similar stuff. That was great! That's how I fell in love with the goose.
