Because that is the correct answer.

Code (fw): Select all Collapse

aLines  := HB_ATokens( "one", "|" )
? aLines // -> { "one" }

alines:= {}

This doesn't help either.

ok and if the cString is empty ( i not Know what is on Cstring, so it can be also empty) How set alines ?
because then I must set another two array from alines

oImage:=array(len(aLines)+1)
aImages:=array(len(aLines)+1)

how I can resolve ?
