Here's how I do it with spasm (which should automatically sign the app for you if you run
"spasm app.asm app.8xk")
Code: #include "app.inc"
defpage(0,"APP")
start:
bcall _JForceCmdNoChar
validate()
And app.inc:
Code: ; Fatal error macro. Displays message prefixed with "error"
; and returns with error code
#define fatal(str,return) .error str
#macro defpage(page, appname)
#if page = 0
#ifndef gpage
#define free_space 0
#define gpage 0
#ifndef appname
.echo "Warning: No name given, using \"Default\""
#define appname "Default"
#endif

.db $80,$12,1,4

#define gappname eval(appname)
_ .db appname
#define apnamlen eval($ - -_)
echo_fill(apnamlen,"-","------------------------------------------")
.echo "Beginning APP \"",appname,"\", courtesy of SPASM macros"
echo_fill(apnamlen,"-","------------------------------------------")
#if apnamlen <= 8
.fill 8-apnamlen,' '
#else
#define err "App name is ",apnamlen-8," character(s) too long."
fatal(err,1)
#endif
