DCCOPTS
This will pop up a requester allowing you to save the currently set compiler options in VisualMaker to the DCCOPTS environment variable. Three options are available:
SAVE
Options are saved permanently in ENVARC:DCCOPTS.
USE
Options are saved in ENV:DCCOPTS and will be gone when computer is turned off (provided your ENV: directory is in ram:).
CANCEL
Self-explanatory.

check %lf
This option causes VisualMaker to search for any output of float-point numbers in the source code and if found automatically set the "-lm" option in the DMakefile which causes the compiler to link with math library enabling output of float and double numbers (if not used float numbers are literally ouput as "<float>"). The program does not actually look for a
                    '(s|f|v)printf("%...f")' 
command but rather just the format string
                   "%[0-9.l+-\*]*(E|e|f|F|g|G)",

that is it does not know whether the expression is inside a printf- family type of command or just a simple string. The option is on by default but if it causes any problems due to the above mentioned, just turn it off (the -lm option increases the executable size).

EXIT
Leave program without writing the DMakefile.
