☜ | Number of Subscripts1995 Version of ANSI (Equivalent to Current ISO Version) of Standard | ☞ |
There is no explicit limit on the number of distinct local variable nodes which may be defined, but there is an implicit limit based on the number of subscripts that may be defined for any local variable reference. The number of subscripts in a local variable is limited in that, in a local array reference, the total length of the array reference must not exceed the maximum string length (see 2.8). The length of an array reference is calculated as follows:
assuming an array reference in the form
name(i1,i2, ...
,in)
N = $L(name)
I = $L(i1) + $L(i2) + ... +
$L(in)
where each subscript (i1 through in) is either a numlit or a sublit
L = n
then the total length of an array reference is
N + I + ( 2 * L ) + 15
