I did not realize that.

The original code I had (dating to several years ago, before anonymous
structures were introduced) used in fact a much more complex mechanism.

It wrote the structure definition (without use of CREATE_STRUCT which
did not exist) to the temporary.temp file

then wrote a xxxtmpnnn.pro file with nnn increasing each time, which
contained the invocation of @temporary.temp (and passed back the
created structure as argument)

then built a string with the invocation of xxxtmpnnn.pro
and used execute to invoke it

When I did now some simple tests, I thought that the above arrangement
was become unnecessary now with create_struct and anonymous structures.
I wanted to simplify it and hoped it were NOW possible.

Apparently I cannot do execute('@temporary.temp')

Is there any limitation to the string length in execute(string) ?

I used a temporary file because the structure definition is rather long,
and is constructed in steps (driven from a data file) ... for legibility
temporary.temp has the statement on several lines (terminated by the $
continuation marker but last one)

If there is no limitation I could concatenate the pieces of the
statement instead of writing them to temporary.temp and just execute the
resulting string.
