OS_SetVarVal not translating error block

Details by Richard Coleman (3190):

As noted by nemo on his twitter feed, deleting a non-existent system variable
<pre><code>SYS “OS_SetVarVal”,“NotHere”,,-1</code></pre>

results in the error message:
<pre>System variable ‘%0’ not found</pre>

whereas reading a non-existent variable with:
<pre><code>SYS “OS_ReadVarVal”,“NotHere”,,-1</code></pre>
returns the error message:
<pre>System variable ‘NotHere’ not found</pre>

Fix is a change to Kernel.s.Arthur2 (Not tested but matches call to RVVNotFound)

Replace:
<pre><code>SetVarVal_DeleteIt
BL VarFindIt

</code></pre>

with:
<pre><code>SetVarVal_DeleteIt
BL VarFindIt

</code></pre>

And just before label “SetVarValBadExit_Translate” add:
<pre><code>SVVNotFound
[ International
MOV r4, r0
ADRL r0, ErrorBlock_VarCantFind
BL TranslateError_UseR4
|
ADRL r0, ErrorBlock_VarCantFind
]
SETV
B SetVarVal_TestVExit
</code></pre>
