I modified one line of code in '*cmd/system/ver' a long time ago to account for this.
if all_ver then goto NEXT_VER
I went back and forth between two options:
if all_ver then if mod(prg_ver,20)=0 then escape end_if ; goto NEXT_VER
if all_ver and prg_ver<20 goto NEXT_VER
Just depends on if you want it to only show 20 versions or if you want it to escape after printing 20 versions. Having it escape is a nuisance, but allows you to either RUN to see more or END.
