Error Codes and Error Flags
Note 1. C101 to C2FF will be stored for FALS numbers 001 to 511.
2. 4101 to 42FF will be stored for FAL numbers 001 to 511.
3. The contents of the error flags for a duplicate number error are as follows:
Bits 00 to 07: Unit number (binary), 00 to 5F hex for Special I/O Units, 00 to 0F hex for CPU Bus Units
Bits 08 to 14: All zeros.
Bit 15: Unit type, 0 for CPU Bus Units and 1 for Special I/O Units.
4. Only the contents of A295 is stored as the error flag contents for program errors.
5. A value of 0000 hex will be stored as the error flag contents.
A200.11: First Cycle Flag
A200.15: Initial Task Flag
A200.15 will turn ON during the first time a task is executed after it has reached executable status. It will be ON
only while the task is being executed and will not turn ON if following cycles.
