The 81000002 and 81000004 task errors get reported if an integer to string or integer to hex string function is called and the caller specifies to allow zero characters to be used for the conversion.

A customer mistakenly caused this by specifying zero characters to print a bundle number. This shut down their entire factory since they rely on this one machine for all of their production.

Rather than shut the whole controller down for a simple mistake, the decision was made to do what the function arguments said to do and use zero characters, in other words, set the string to zero length or add zero characters depending on if it was a copy or add string function call.
