Adjust value of number by given amount

Help neededvery quickly please - seriously short deadline!
I have many levels on section drawings. All level info is dtext (ie 34.567). NOT BLOCK ATTRIBUTED.
All values need to be decreased by a constant given amount (ie 0.075).
Can I do a global subtraction/addition to text instead of changing each value seperatley? (ie 34.567-0.075=34.492)
If anyone has a routine already I would be most grateful of it asap.

Many thanks,

Kieren,

Get all the text you want in a selection set, then step thru it one by with getting "assoc 1" of the text. Then subtract that value by a value you set, then with the answer substitute it back into the original text entity.

Can you select only the text entities that need to be incremented? Here's a program I wrote to do something like this to a land survey drawing where there were a couple thousand elevation shots as TEXT entities, and I needed to change the datum. FIXDATUM asks you for how much you want to increment the number values, then in each TEXT entity among those you select, it looks for the first substring that looks like a number and increments that number by the value you entered, then it modifies the text value so it shows the number plus the increment value you entered earlier, displayed to the same number of decimal places as were originally there. For example, if I say I want to add 2.54 to the values, and I select four TEXT entities with these values:

"hello"
"12"
"24.1"
"30.1324 15.2"

the new values are

"hello"
"15"
"26.6"
"32.6724 15.2"

 

The code for checking to see if it's a number is: (if (numberp (read "string
goes here")) (then_do_whatever))

A little more info. would be helpful. For example, do all the text strings
share a command pattern, e.g. "Elev.=34.567" or they are just strings with
numbers?

value seperatley? (ie 34.567-0.075=34.492)

 

File sent, it is from Cadalyst.com.

The command you suggest is quite different from what the poster was asking
for. They wanted to increment existing numbers by a set amount. The ET you
suggested creates but does not adjust existing text.

From the ET help file.
"TCOUNT - Adds sequential numbering to text objects. The numbering can
appear as a prefix, suffix or replacement text. "

Kal, I hit send before I was ready. I was trying to check the ET tool
TCOUNT but the ET's aren't working on ABS today. You may be correct about
that command working for what they needed. I can't confirm for myself, but
my apologies if I was wrong in the other post.

Kal
The ET command TCOUNT will not do what the original poster asked for.
