There are two ways to do this that are completely portable:

(1) Create the record in VEE ascii format as a string and feed to a
"from string" object reading in "container" format. This requires a
little bit of work to understand the ascii format, and it could
likely break at future releases but is otherwise quite simple.

(2) Write a utility - say strReplace(str, old,new)- that replaces
occurences of one string with another. Then create a record with dummy
names, write that record to a string, replace the names, and then
read into a record using a "from string" object. This is a
little slower and clumsier but should also be more robust since
you are not relying upon the VEE ascii syntax. This is what I
have done for our user group here and it works great.
