I need to remove trailing chr(0)'s from a null terminated string. I gathered from VFP help that I should be able to do this by...

SET LIBRARY TO STRLEN
cTest = "Hello"+repl(chr(0),10)
nLen = STRLEN(cTest) && should return 5
cString = LEFT(cTest, nLen)

but no such library exists as far as I can tell.
Can anyone shed any light on this for me?

TIA
