1597 237 d 1 h mateusz.viste /svarcom/trunk/ save (and restore) the original parent of my PSP as advised by E. C. Masloch  
1595 237 d 19 h mateusz.viste /svarcom/trunk/ set parent of transient SvarCOM to RMOD (apparently required by EDR-DOS?)  
1594 237 d 20 h mateusz.viste /svarcom/trunk/ preserving bx,cx,dx registers throughout inline assembly block  
1591 240 d 19 h mateusz.viste /svarcom/trunk/ instead of raw-copying a PSP for RMOD, ask DOS to generate it via int 21h,ah=26h  
1590 241 d 3 h mateusz.viste /svarcom/trunk/ do NOT close file handlers in an attempt to preserve the stdin/stdout/etc descriptors  
1589 241 d 4 h mateusz.viste /svarcom/trunk/ RMOD's PSP set so the SS:SP pointer has some room to POP things (advised by E. C. Masloch, thanks\!)  
1588 241 d 7 h mateusz.viste /svarcom/trunk/ preset RMOD's JFT size to 20 slots (which is the maximum that the PSP can hold - more than this would require a separate allocation)  
1587 241 d 18 h mateusz.viste /svarcom/trunk/ patching up RMOD's PSP once it is loaded in memory: clearing out the JFTand presetting a stack address. thanks to E. C. Masloch for pointers  
987 869 d 9 h mateusz.viste /svarcom/trunk/ improved stack overflow protection so it is allows stack overflow as long as it does not touches actual data  
983 869 d 21 h mateusz.viste /svarcom/trunk/ smart stack overflow detection: damages only the commandline history and degrades gracefully  
975 871 d 17 h mateusz.viste /svarcom/trunk/ transient shell follows the int23h vector to locate RMOD (LINK/LN compatibility workaround)  
963 871 d 21 h mateusz.viste /svarcom/trunk/ rmod bat ctx linked list is freed using a specialized function to enable reusability  
957 872 d 18 h mateusz.viste /svarcom/trunk/ CALL support for calling batch files from within batch files  
949 873 d 3 h mateusz.viste /svarcom/trunk/ redesign of how batch contexts are stored in memory (required for future CALL support)  
537 962 d 19 h mateuszviste /svarcom/trunk/ added break handler  
479 969 d 21 h mateuszviste /svarcom/trunk/ cmdline far ptr is replaced by a local array, shared with BUFFER and merged with rmodcore  
478 970 d 2 h mateuszviste /svarcom/trunk/ renamed rmod array to rmodcore and removed its const flag so the memory can be possibly reused for other purposes  
475 970 d 4 h mateuszviste /svarcom/trunk/ rmod->echoflag merged inside rmod->flags  
465 971 d 21 h mateuszviste /svarcom/trunk/ rmod stacking is possible (multiple command.com instances) + minor optimizations  
459 972 d 20 h mateuszviste /svarcom/trunk/ rmod has a PSP now  
454 973 d 8 h mateuszviste /svarcom/trunk/ simplified rmod_install()  
453 973 d 8 h mateuszviste /svarcom/trunk/ saving original env seg in rmod so I can detect "I am process 0" situations in MS-DOS 5/6  
450 973 d 23 h mateuszviste /svarcom/trunk/ moved some data into rmod props struct  
449 974 d 2 h mateuszviste /svarcom/trunk/ implemented /P and a generic rmod memory buffer for transient-only settings  
448 974 d 22 h mateuszviste /svarcom/trunk/ each svarcom instance has its own rmod + svarcom is able to quit (unloading its rmod in the process)  
439 977 d 0 h mateuszviste /svarcom/trunk/ use env_lookup_val() when possible  
421 980 d 19 h mateuszviste /svarcom/trunk/ documentation improvements and added licensing information to all src files  
397 987 d 1 h mateuszviste /svarcom/ moved contents to trunk  
369 994 d 20 h mateuszviste /svarcom/ replaced printf() calls by outputnl()  
367 997 d 1 h mateuszviste /svarcom/ shell sets COMSPEC to self at starts  
366 997 d 20 h mateuszviste /svarcom/ shell is loaded from COMSPEC whenever COMSPEC exists  
359 999 d 3 h mateuszviste /svarcom/ always mark my env segment as self-owned, otherwise it will be freed as soon as SvarCOM transient part terminates  
358 999 d 9 h mateuszviste /svarcom/ extra checks when looking for resident part to avoid false matches  
351 1000 d 4 h mateuszviste /svarcom/ rmod-related routines moved to a separate module
