Under X the X server + can be established or changed on the fly by channging + the value of the DISPLAY environment variable. + + String slicing operations ZX Basic style using [ ]. + + Added SCROLL, ZX_PLOT and ZX_UNPLOT instructions. + + Additional optional parameters for COPYCHR$. + + Characters redefinition Spectrum style now extends + to Z. + + LABEL can be used as function, giving the line number + where the label is defined. Useful with 'IF ERL = ...', + for example. + + RENUM takes another optional argument, to stop + renumbering at certain line. + + Changed default charset, added charsets spectrum and + cpc, selected when used the corresponding command + line option and with a new syntax for SYMBOL AFTER. + + RETURN now admits an optional line number argument. + + FN RETURN instruction added. + + POPEN now can be bidirectional and capture the error + output. This feature may or not works well in windows, + depending on the windows versions, more work in this + is needed. + + CHAIN MERGE now does not affect the current program + if the loading of the chained fails. + + Line number 0 is now valid (and you can even ON ERROR GOTO + to it, but only with a LABEL). + + New machine type command line option --appleII + + New operator \ for integer division. + + New system flags to control if true value is -1 or 1 + and if the logical operators are binary or boolean. + + GO TO and GO SUB are now accepted. They can be listed + as two words using a new system flag. <= and others + also are accepted with embedded spaces. + + New system flag to allow GOTO and other jump instructions + refer to a line number inexistent, using the next line in + that case. + + New command line options --errout, --norun, --tron and + --tronline. + + Processing of command line options reworked. Now a option + inexistent is not taken as a filename, generates an error + instead. + + Better LABEL caching and error detection. + + Now can be compiled without graphics in platforms where + they are supported just by commenting the line + #define BLASSIC_HAS_GRAPHICS + in graphics.cpp + + Added flag in system vars to control if debug info is showed + on certain errors, and --info command line option to turn + it on. More debug info added to be used with this. + + Added UCASE$ and LCASE$ aliases for UPPER$ and LOWER$. + + Added GET and PUT graphic variants. + + Corrected bug of LINE ... B in windows. + + Added function ALLOC_MEMORY and instruction FREE_MEMORY, + this allows use of machine code in operating systems with + protection against execution in data areas. + + Regular expression functions (currently not working under + windows). + + INSTR with initial value less than 1 now gives error. + + Corrected READ: now a comma at the end of a DATA sentence + is valid. + + EOF now works with random files.
