You need to supply more information. Do you want the parametric program to calculate the X,Y coordinates based on variables set by the user, or do you want just a program that will perform a repeat of X,Y clearing data until to depth with a given depth of cut.

The t slot is big, so i need a program that is gone calculate x and y from the midle to the finished contur, and repeat that to the final depth. I think i can do the loop for z increment, but i need hellp with the pocket program.

you still need to supply a basic sketch with some sizes at least otherwise we can't write the program and also the diameter of the cutter you intend to use.

As you can see on the attachement, i am trying to get this parametric program because i have hundreds of diferent geometries for this pokets. 'A' and 'B' dimensions are variables for diferent parst.

is corner radius always the same or should be parametric? Same thing for the angle of the lines that join the large and the narrow part of the T and the length of the narrow part. Also, How "A" dimension can be 0???

A dimension in the tabel is 0 just to show what is the other dimension at that point. Radius does not mater depending on the smaler T side is the radius of tool. Same for the angle

if the T shape can be just two rectangle perpendicular each other with tool radius in the 6 outside corner and sharp corner in the 2 inside corner it could be easy enough to program but with radius in the inside corner and angle on the junction of the two rectangle, it involve a lot of calculation. Let me know if we could simplify the shape like i suggest, and i'll can try something

hundreds? there's 9 different size pairs. the shape is mirrored so you only need to program half of it then apply X mirror image if you are low on memory. if not, why can't you just write the program long hand, it's really not that difficult. certainly not something that needs macro programming to do it. program should be 5-10 minutes each. so say 9x10 = 90 minutes to write 9 programs with copy/paste and change a few sizes. since this is a pocket you can rough mill a 'T' shape then machine around the shape profile with the cutter in one pass using G41/G42.
btw the drawing you supplied is still not good enough to write the program. you need to provide all sizes or program can not be done. i.e. distance from top to angle step and radius, or intersection point of angle face and side face and either angle of tapered line or intersection point of angled line and lower 'T' vertical line and width of lower 'T' section.
In other words it can not be done at all with the info you provided.

I agree that information is not complete, but just to put everything parametric and nothing could be missing. We cannot say that dimension is missing in parametric programming, cause dimensions are variable.
