global variable with null stuff in it.

Dealing with programs for Lark

PatchItem: TYPE = REF PatchItemObject;

PatchItemObject: TYPE = RECORD [

Program: TYPE = REF ProgramObject;

ProgramObject: TYPE = RECORD [

Enumerate all programs on tap.

EnumeratePrograms: PROC [proc: PROC [program: Program] RETURNS [stop: BOOL]];

Search for the given program on the list of parsed programs

FetchProgram: PROC [programName: Rope.ROPE] RETURNS [p: Program];

Put the given program on the list of parsed programs, replacing a previous copy

AddOrReplaceProgram: PROC [program: Program];

Reset the patch list associated with the program. program.patchList ← NIL

ResetPatchList: PROC [program: Program];

Reads the program, but does not store it in the data base (use AddOrReplaceProgram)

ReadProgramFromDisk: PROC [objectFileName: Rope.ROPE, log: IO.STREAM ← NIL, addressSpace: TeleLoad.AddressSpace ← main, wDir: Rope.ROPE] RETURNS [Program];

ReadProgramFromMBFile: PROC [mbFileName: Rope.ROPE, baseAddress: TeleLoad.CoreAddress, log: IO.STREAM ← NIL, addressSpace: TeleLoad.AddressSpace ← main, wDir: Rope.ROPE] RETURNS [Program];

Read symbol tables for the program. Used internally by Monitor and ReadProgramFromDisk, probably not needed externally.

BuildSearchTable: PROC [program: Program, name: Rope.ROPE, log: IO.STREAM ← NIL, wDir: Rope.ROPE];

Add a patch item to the list for the given program.

PatchProgramWord: PROC [program: Program, address: TeleLoad.CoreAddress, wordValue: CARDINAL, name: Rope.ROPE ← NIL];

Read patch items from the given file, checking symbol names against the symbol table for the given program.

PatchFromFile: PROC [program: Program, fileName: Rope.ROPE, log: IO.STREAM ← NIL, wDir: Rope.ROPE] RETURNS [LIST OF PatchItem];

Symbol table access. ProcedureEnclosing is handy for printing stack traces. It finds the symbol with the next lowest address. (Note: works fine for finding the static symbol most nearby.) If searchMonitor = TRUE, then the search will include monitor symbols, if any can be found.

ProcedureEnclosing: PROC [program: Program, addr: TeleLoad.CoreAddress, searchMonitor: BOOL ← TRUE, wDir: Rope.ROPE] RETURNS [s: STObject];

Usual kind of symbol table lookup. If searchMonitor = TRUE, then the search will include monitor symbols, if any can be found.

FindVariable: PROC [program: Program, name: Rope.ROPE, searchMonitor: BOOL ← TRUE, wDir: Rope.ROPE] RETURNS [item: STObject, found: BOOL];

Return, if possible, a handle for the EPROM monitor for Lark. This is useful for looking at monitor statics.

Monitor: PROC [log: IO.STREAM ← NIL, addressSpace: TeleLoad.AddressSpace ← main, wDir: Rope.ROPE] RETURNS [mon: Program];
