mid confusion
« on: August 07, 2019, 01:54:23 AM »
Charles,
  I notice you put padstr and numstr in StringUtil.
Would you please explain the mid(s,-dp ) in this line???
Code: [Select]
s=ng+left(s,ls-dp)+"."+mid(s,-dp)

Thank you.

Hi James,

A inegative index in mid counts from the right, instead of the left:

Code: [Select]
string s="abcdef"
print mid(s,-2) 'ef

Yes, the o2 right is a macro based on mid.
