Internal Error # 332
String/Array memory overflow
----------------------------------------------------------------------------------
The maximum capacity of the Segment Virtual Object Store (SVOS)
system has been exceeded. Because of the dynamic nature of SVOS, it
is impossible to state exactly when this error will occur (see the
Release Notes database in Norton Guides, "5.01 Notes" under "Runtime
Memory Management"). In the worst case, this error will occur when
slightly over a megabyte of strings and/or arrays are in use; the
best case is in excess of 16 megabytes.
Action: This problem can be resolved by reducing the size and/or
number of strings and arrays that are active at any one time.
Probably the most common cause of this error is the declaration of
extremely large arrays (e.g., LOCAL aArray[500][300]). Note that
every array element requires memory to store -- even if its value is
NIL -- and that the number of array elements in an array is
determined by multiplying the number of elements in every dimension
and adding the sum of all dimensions except for the last. For
example, a 500x300 array has (500x300) + 500, or 150,500, elements.
Because every array element in Clipper requires 14 bytes, this
amounts to 150,500 x 14, or 2,107,000 bytes -- well in excess of one
megabyte and therefore potentially dangerous.
Note: There is no benefit gained by reusing arrays. Clipper is much
more efficient when strings and arrays are thrown away and rebuilt
often rather than kept around unnecessarily for long durations.
