V. CP - Constant Pool
Constants needed by the object program are pooled together in a block of storage immediately following the Positional Indicators. An example of a reference to Constant Pool cells might be:
CAL CP)+11
ANA CP)+22
VI. GN - Generated Name
During compilation it is necessary to give certain instructions names in order to refer to these instructions from a remote part of the program. Names are generated and placed on such instructions and might appear in the listing as:
TSX GN)019,4
GN)019 CLA PI)3
VII. SYS - System Subroutines
There will be many references in the listing to subroutines which are not part of the binary deck produced by the compiler. Typical references to such subroutines might appear in the listing as:
STI SYS)133
TSX SYS)182,4
TXI SYS)243,1,84
These System Subroutines are contained on the System Tape and are brought into core, as needed, by the CT LOADER. The function of each of these routines and an explanation of the calling sequences that appear in the listing are explained in the latter part of this Appendix.
VIII. IOC - Input Output Subroutines and Communication
References to Input/Output subroutines and communication cells appear in the listing in the form IOC)NNN. Typical references to IO routines or communication cells are:
TSX IOC)9,4
MZE IOC)17
PZE IOC)29
Most of these are routines that are a part of the CT monitoring system which is in core at all times. The function of each routine is explained in the latter part of this Appendix.
