Marie-Edith,
Thanks for reporting this, and figuring out the answer. I've updated the
manual and the error feedback within the function so it should be easier
to figure out for others in the future. For the record, if the target is
not found it returns the value 0 (i.e., false).
This function is a compiled function, written in c++. If you download the
source, you can find its definition at
src/libs/PEBLString.cpp
But it is really a wrapper for something buried within the string-handling
classes. Many functions are written within PEBL code, and appear in the
pebl-lib\Utility.pbl or pebl-lib\Math.pbl or pebl-lib\Design.pbl files.
Although this function could have been written in PEBL using Substring(),
but I think I chose to use a compiled version for the sake of speediness.
