I am not sure what you mean. The words ?initial context? in the
documentation and output refer to the state of variables just before the
analysis starts. These values are influenced indirectly by option ?-main f?
and directly by options ?-lib-entry?, ?-context-width n? and
?-context-depth n?, all found in the manual under:

5.2 Describing the analysis context

If these options are not enough for what you want to do, write you own
analysis entry point that sets up the variable in C and then call the real
entry point of the program.
