Here is the procedure I undertook, to hopefully shed some more light:
1. First I added a new variable to the config struct in
src/include/emu.h called delay_interval
2. in src/base/init/lexer.l.in:
delay_interval RETURN(DELAY_INTERVAL);
3. in src/base/init/parser.y.in:
%token DELAY_INTERVAL
4. in src/base/init/parser.y.in also:
| DELAY_INTERVAL expression
{
c_printf("Hello, this is delay_interval speaking\n");
}
5. in global.conf, under checkuservar, I add $_delay_interval.
In the parser_version_3 scope, I add:
delay_interval $_delay_intervala
6. in dosemu.conf on my system, I add $_delay_interval = (1234)
7. I run the new dosemu.bin -D+C, and my c_printf is never displayed.
Any ideas?
