OK, this is pretty amazing. Turns out the compiler can handle functions.
Took me most of the day, but believe it or not, now you can:
1) write macros that look like commands:
function coloritgreen
color atoms green
end function
delay 1; coloritgreen; delay 2
2) write subroutines that accept parameters:
function drawline(id,atom1,atom2)
var x = script("draw line"+id+" {atomno="+atom1+"} {atomno="+atom2+"})")
end function
[note the localization of the variable x using the "var" keyword, like
JavaScript
3) write your own math functions:
function dist_nm_rounded(a,b)
return (a.distance(b) * 100)%0
end function
x = dist_nm_rounded({atomno=3},{atomno=4}) / 2
print dist_nm_rounded({atomno=3},{atomno=4})
You can nest up to 10 scripts and functions. That could be higher -- 10
is totally arbitrary.
