Remove leading zeros

[bhca60]

How do i remove leading zeros for a variable with values that look like this:

00099V67
000123

Some have two zeros in front some have three.

You apparently have a character variable, since one of your sample values has the letter "V" in it.

First, and definitely foremost:  why do you want to remove leading zeroes from a non-numeric variable? 

Let's say you did so.  Then, since your sort order is lexicographic, instead of sort order of

000999
002231
011577

with leading zeroes removed (and the remaining characters left-justified) you would have this order:

11577
2231
999

Do you really want that

This has been asked before, you could search and see if you can find the older discussions.

This is what the VERIFY function is good at.

data have;
  input str $12.;
cards;
00099V67
000123
12345
;

data want;
  set have;
  if verify(trim(str),'0') then str=substr(str,verify(str,'0'));
run;

What does your variable represent? Leading zeroes can have meaning in character variables and could be dangerous to remove.

data want;
  set have;
  want=prxchange('s/^0+//',1,strip(str));
run;
