we use 4.0.1 (on VMS 6.13.2G)

it is not a border for the string-length, i successfully created
structures with execute having a string of 1500 Chars...

it is

a) a problem of comma (,): you cant use more than 123 my
knowledge or the function-parameter-transfer will fail

b) a problem of tag-types: if you create a lot of different types
of tags, than the execute will fail with programm code area fail!

I contacted Creaso on it and they can reproduce the error with
my fail.pro on each plattform (see X-Mas- survey). My fail.pro
changes the tagtyp everytime (which is worst). In this case the
execute will fail at the 24th tag! The length of the string is
void!

c) Mr. Allewelt from Creaso contacted RSI and is working on this
problem.

you can do a work arround by doing a iterative create_structure
call in a execute-simulating-routine! I have written such a routine
to be able to work with more than 24 tags, but the routine
is about 100 times slower!!!

Creating a structure is lasting about 1-2 secs in this case, which
is much to long!
