Hello,
I'm running J903 in windows
I made a programming mistake in setting the rank of the verb
"index_of" that crashed the system.
I have an array A (years x observers x days) containing integer values.
I want to determine the location (ie day index) of a pre-determined value
for each year x observer. Hence array B is (Years x observers)
I should have coded
result =. A i."1 0 B
but I coded
result =. A i."1 B
which crashed the system without any error messages etc.
For example -
JVERSION
Engine: j903/j64avx2/windows
Release-a: commercial/2021-12-16T15:15:09
Library: 9.03.08
Qt IDE: 1.9.5s/5.15.2(5.15.2)
Platform: Win 64
Installer: J903 install
InstallPath: c:/utilities/j/j903
Contact: www.jsoftware.com
A =. 10 800 400 ?@:$ 100
B =: 10 800 ?@:$ 80
result =. A i."1 0 B NB. Works OK
result =. A i."1 B NB. Crash !!!
