#SEGMENTCONVERT Built-In Function
°
Whenever a RVU of TACL after C10 tries to attach a C00/C10 segment file, it
automatically creates a temporary segment file in format version C20 or later,
copies the older file to it, and attaches the temporary file instead. This typically
happens every time you log on. Converting the older file to the newer format
eliminates this action, as well as the disk space requirements of the temporary
file.
°
If you create a variable with a C20 or later RVU of TACL, and the variable
contains a “y-dieresis” character (in the international character set), and you
write the variable to a C00/C10 segment file, it can corrupt the file. Converting
the file to newer format eliminates that risk.
•
Conversely, a newer segment file cannot be attached by a C00 or C10 RVU of
TACL. #SEGMENTCONVERT can convert such a file to the older format. To
obtain the version of a segment file, use the #SEGMENTVERSION built-in
function.
•
You cannot attach more than 50 segment files.
