Number of Subscripts

Draft MDC Standard

☞

2.3.2 Number of subscripts

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 510 characters. The length of an array reference, assuming it is in the form name ( i1 , i2 , ... , in ), is calculated as follows. If:

    N = $Length(name),
I = $Length(i1) + $Length(i2) + ... + $Length(in), where each subscript (i1 through in) is either a numlit or a sublit, and
L = n,

then:

    the total length of an array reference = N + I + ( 2 * L ) + 15.
