Size Limits for ACL Variables
There is no size limit for a string-valued variable. However, the command parser limits the size of any command argument or string token to 4095 characters. For example, if both $b and $c are 2500 characters long, then the following example creates a variable that is 5000 characters:
$a = $b . $c
The variable $a shown above is too long to be substituted into a command at the Arbortext Editor command line. Therefore, typing the following would result in a parser error:
find "$a"
This variable could, however, be used in an expression or function call. Here is an example:
$d=substr($a,1500)
insert($a)
The show variables command gives you a listing of all defined variables and their values.
