Some versions of the Algol compiler had a bug which gives bad results for some expressions involving numeric constants. This change avoids the bug.
The previous version introduced a but that prevented Waitwatcher working for large mix numbers (i.e. > 9999).
As far as can be determined the Family substitution code hase never worked for big mix numbers.
On systems running with OP+MORETASKS set, WAITWATCHER was failing to process operator commands such as FA and IL because of an error in the SETSTATUS command format. This problem, which led to WAITWATCHER errors such as 'CANNOT FIND VALID REPLY' being seen, is now fixed.
WAITWATCHER will now detect unit numbers greater than 4095 for commands such as HO and FP. The internal version number has also been changed for 49.1 compatibility.
This change is only to change the version number to 48. Version 470.03 is valid on MCP 4.8.
Patch 470.02 inadvertently caused WAITWATCHER to unconditionally F-DS with integer overflow when checking MCP levels. This fault has now been fixed.
