lappend size limit???

[David Plunkett]

Does anyone know if there is a size limit on a variable created with the lappend command?

I’m running the following code and it’s bombing after about 246,000 records with “Illegal instruction(coredump)”.

foreach record [split $inFileData n] {

  lappend newData [format “%-300s” $record]

}

Thanks

Not sure of your OS, but on Unix, yes there’s a limit.

I don’t remember which parameter it is, but it is in this list:

$ ulimit -a

time(seconds)        unlimited

file(blocks)         2097151

data(kbytes)         131072

stack(kbytes)        98304

memory(kbytes)       98304

coredump(blocks)     2097151

nofiles(descriptors) 2000

I ran into a similiar problem and had to write information out to a file after x number of records to keep the script from core dumping.
