i wrote a program ;

Declare sub makefont (x%,y%,color%,size%,typ%)
'no loop

sub makefont (x%,y%,color%,size%,typ%)
'a little code
end sub


i saved it as a library and then

'$include: 'font.lib'
call makefont(x%,y%,...etc.)

this couldn't recognize back the sub makefont..There was some yellow chr$ codes on the screen..

Now i wonder how can we save our subs and recall them from
our libraries ?..

Or does it mean that i missunderstood the mentatlity of libraries ?..
Help pls..

You have to start qbasic with the /L parameter. This tells qbasic to support libraries.

put:
Declare sub makefont (x%,y%,color%,size%,typ%)
in your program.
not...
'$include: 'font.lib'

if anything place:
'$include: 'font.BI'

(Basic Include)

which would simply include the text:
Declare sub makefont (x%,y%,color%,size%,typ%)

so for that matter just place the line in your program instead of the include.

the /l switch is what loads the library, not the '$include

Does QB create the BI?

(btw, you have to go /l then your lib name, otherwise it just loads qb.lib/qbx.lib/vbdos.lib depending on your version)

No...

You make a blank text file.

Copy/Paste your declarations into it...

Such as:
Declare Sub/Function ...
Type MyType
X as ...
Y as ...
End Type
Dim Shared Var As ...
Const PI = 3.1415
etc...

Then save it. The .BI extension is optional (It stands for Basic Include)

This is more or less the equivalent of a header (.H) file in C/C++

the difference is (I think... it has been awhile) in basic you can only include 1 file. in c/c++ there is no limit.

Also you can not place commands in include files in basic.
(such as X = Y + 1, or SCREEN 13)

----------------------------------------------
/L (by itself) loads QB.QLB

/L MYLIB loads MYLIB.QLB

when you create EXE, your MYPROG.BAS generates MYPROG.OBJ which is then linked with QB.LIB (or MYLIB.LIB respectively) to create MYPROG.EXE


Details:
MYLIB.BAS is compiled and creates MYLIB.OBJ
MYLIB.OBJ is linked with QB.LIB to create MYLIB.LIB using LIB.EXE
MYLIB.LIB generates MYLIB.QLB using LIB.EXE

MYLIB.QLB is loaded into QB using /L MYLIB

MYPROG.BAS is compiled and creates MYPROG.OBJ
MYPROG.OBJ is linked with MYLIB.LIB to create MYPROG.EXE using LINK.EXE
