Hallo, guten Tag.
Ich spiele mal kurz mit dem QBX (Basic PDS 7.1)
Kann man dieses Programm von Pascal compilieren um es im Basic zu Linken?
Was bedeutet MODULE für TP 6.0 ?
Wenn ich es compiliere kommt eine EXE raus. Das ist aber nicht sinn der Sache nehme ich an ?
Danke.
Code
{ **********************ADDSTRING ***********************
{ Module MXADSTP--takes address and lengths of two BASIC
strings, concatenates, and creates a BASIC string descriptor. }
MODULE MAXADSTP;
{ Declare type ADSCHAR for all pointer types. For ease of programming,
all address variables in this module are considered pointers to
characters, and all strings and string descriptors are considered
arrays of characters. Also, declare the BASIC string descriptor
type as a simple array of four characters. }
TYPE
ADSCHAR = ADS OF CHAR;
ADRCHAR = ADR OF CHAR;
STRDESC = ARRAY[0..3] OF CHAR;
VAR
MYDESC : STRDESC;
{ Interface to procedure BASIC routine StringAssign. If source
string is a fixed-length string, S points to string data and SL
gives length. If source string is a BASIC variable-length string,
S points to a BASIC string descriptor and SL is 0. Similarly for
destination string, D and DL. }
PROCEDURE STRINGASSIGN (S:ADSCHAR; SL:INTEGER;
D:ADSCHAR; DL:INTEGER ); EXTERN;
FUNCTION ADDSTRING (S1:ADSCHAR; S1LEN:INTEGER;
S2:ADSCHAR; S2LEN:INTEGER) : ADRCHAR;
VAR
BIGSTR : ARRAY[0..99] OF CHAR;
{ Execute function by copying S1 to the array BIGSTR, appending S2
to the end, and then copying combined data to the string descriptor. }
BEGIN
STRINGASSIGN (S1, 0, ADS BIGSTR[0], S1LEN);
STRINGASSIGN (S2, 0, ADS BIGSTR[S1LEN], S2LEN);
STRINGASSIGN (ADS BIGSTR[0], S1LEN+S2LEN, ADS MYDESC[0], 0);
ADDSTRING := ADR MYDESC;
END; { End Addstring function,}
END. {End module.}
