C-2 Application Restrictions
In a Tag of a User-defined Data
Type, an Instruction May Write
Past the End of an Array. If you write too much data to an array that is within a user-defined data type, some instructions write beyond the
array and into other members of the tag.
Example 1: Instruction Stops at the End of the Array
If the length is greater than the number of elements in
the destination array . . .
. . . then the instruction stops at the end of the array.
Example 2: Instruction Writes Beyond the Array
If the length is greater than the number of elements in
the destination array . . .
. . . then the instruction writes data beyond the end of
the array into other members of the tab. Regardless of
the length specified for the instruction, it stops writing if
it reaches the end of the tag.
The following instructions write beyond the array into other members of the tag:
BSL FBC LFL
BSR FFL LFU
COP FFU SQL
CPS FLL SRT
DDT GSV SSV
This restriction also applies to all previous revisions.
To prevent writing beyond the limits of the destination array, make sure that the length operand of the instruction
is less than or equal to the number of elements in the array.
