put a Misc integer in buffer for later use in lathe post

[Dave Loveridge]

I am modifiing a V9 lathe post and I want to put a value in the first mi operation of a program and store it for later use. It works somewhat but when I use the value it resets the value to 0 when it is used and when I got to use it again it does not work because the value is 0.

Please help this is frustrating me.

 

Thanks in advance

As I understand it, you are just trying to preserve the value from a

Misc Integer at the start of the program so you can check it (use it) later one.

You mentioned storing it to a Buffer ("Buffer" means an external FILE to a post).

If you just trying to save this ONE misc integer value, that would probably

be overkill. I would just declare a variable to hold that value.

 

Then in the Start of File postblock, capture the Misc. Integer you want to save.

(The postblock would be either LSOF -or- PSOF)

 

code:

---

my_value : 0   # Declare a variable

 

lsof #Start of file for non-zero tool number, lathe

my_value = mi1 # Save value in "mi1" at start of 1st operation.

---

Since this is the only place that "my_value" is loaded with a value,

you know that when you look at it later on in the post, it will hold

the 1st operation (program startup) value.

Yes I did what you said, the problem is once I use it later down in the program it changes it to a zero value, then when I need to use it a second time it is no good.

Try, after your call to my_value "prv_my_value = my_value" on a line by itself.

Can you either post on the ftp or e-mail the post to me? If this is happening the way you suggest, we could all be in for some BIG trouble.
