With how SmileBASIC handles programs, you can (Most of the time) easily compress programs.
Like this:
LOCATE 0,0
PRINT "TEST 123123123"
I$=I$+"12345"
LOCATE.,.?"TEST "+"123"*3INC I$,"12345
This works because:
- It detects
. as a number (Probably the same reason as
.5 is the same as
0.5)
- It runs
DEFs under:
A-
Z and
0-
9, but not
.
- When there's not another separator (
,), it treats it as a newline
-
INC is just
ARG1=ARG1+ARG2,
still works with strings because of how variables are handled
Notes:
- When making something, try not compressing a lot of it, in case you easily want to change something
-
: makes a newline, handy for some
SB commands are optional arguments (Including
PRINT/
? if they have no arguments):
ACLS:?"12345" 'ACLS [GR, SP, FN]
-
DEC won't work as
INC, because it's
ARG1=ARG1-ARG2.
-
DEFs also won't include these:
!,
&,
SPACE/
CHR 0 and
@ but variables
can be defined with
#
- If a line starts with
:, it will return a syntax error
- You don't need to close a string on a newline, but not
: (e.g. ?"123)
- Anything after a
' (Or
REM) on a line will be a comment
These can only be replaced if it's a simple true/false operation (e.g.
#TRUE&&#TRUE #TRUE||#FALSE)
-
OR can be replaced with
||
-
AND can be replaced with
&&
-
NOT can be replaced with
!
-
DIV can be replaced with
/
-
#WHITE or
RGB(255,255,255) is just
-1
- If you want to know what a value is (e.g.
RGB(127,63,255)), then just type in
? then the command in
DIRECT mode and use the shortest one (
#LIME or
-16713728)
-
IF will always execute if it's not
0
-
TRUEand
FALSE are just
1 and
0
- To invert a boolean (
TRUE or
FALSE), use
NUM=!NUM
- If you use something like
STR$[NUM] , it will return the equilivant of:
MID$(STR$,NUM,1)
, but if it's greater than the length of the string, it would return a
Subscript out of range
- If a return call is not made in a
DEF (e.g.
RETURN NUM), it will cause a
Type mismatch
- If a return call return to nothing, it will cause a
Syntax error (This also happens with
"123"STR$(NUM))
- If there's code in the same line as the IF statement, then the command will only run one line until
ENDIF (Only when a newline has been specified with
CHR 10)
-
"123"*NUM is
probably the same reason as how
INC works with strings
Examples: (One per line)
CLS?"Hello, "+USR$
GFILL.,.,399,239,-1
IF LEN(S$)THEN ?"TEST"
NUM=!.
?:GPUTCHR.,.,"HI",#LIME
?.LOCATE.,1?"HI"
ACLS?"TEST"
