Yep, because the VAT is moved around a lot, a pointer to the start of it is stored at {E9830}r. That's how you'd access it in Axe.

I'm trying to parse the VAT for DCS7 folders, and create a new folder, with a user input name and predefined contents.

DCS7 folders aren't stored in the VAT. They're stored in DCS's own appvar (I think).

DCS folders are stored in an appvar, right? i think it's called FLD7 or something. so i guess you'd have to loop through the vat until you find "FLD7" = (name of current entry). then you'd have found the folder appvar, but you'd need to know how DCS' folder system works within the appvar.

edit: right... why not just GetCalc("appvDCSFLDAPPV")->X?

not according to Kerm. According to him, they are protected programs, named %FLDn

where n is a number from 00 to FF.

Yup.  You can see them in CalcSys. :)

Could someone write a routine in Axe that parses the VAT, checks for all %FLDn files, and finds the highest value of n (n1), then creates an Axe name string,  %FLD[n1+1]? That would help me out alot.

Shouldn't be too hard the only challenge, as far as I can see, would be the parsing of the VAT. The rest is just playing with a string. I'm just not comfortable with the VAT enough to do it myself.

As nemo pointed out, Quigibo wrote a few subroutines that can parse the VAT for you. Call sub(VI) to start off. Then, check the current entry's name, which is stored backwards with the first token at sub(VN), call sub(VNX) to move to the next VAT entry, and if not at the end of the VAT, repeat.

If I want to store something into an appvar pointed to by Z, but start at position 1 instead of position 0, would i do

A->Z+1

or A->{Z+1
