Question Hi Alex, i hope you can give me some idea regarding my problem. Can I pass a parameter coming from the outside of the program? For example I have a program named 'PROGRAM.BAS', can I pass a parameter on this by executing PROGRAM Jojo 1234? Wherein the Jojo and 1234 value will be accepted inside the PROGRAM.BAS and manipulated.
Answer Hi, Jojo,
What you'll want is to use the COMMAND$() built-in array. I'm not sure if this will work without compiling the program, though.
To call the script, you'd do something like:
qb.exe yourBasicCode.bas arg1 arg2 3
You'll have to play around with the command to get it working right.
You may want to make a command like this:
FUNCTION HasCommandLine( lookFor AS STRING, index AS INTEGER )
DIM i AS INTEGER
HasCommandLine = -1
IF index < 0 THEN
FOR i = LBOUND( COMMAND$ ) TO UBOUND( COMMAND$ )
IF LCASE$( COMMAND$( i ) ) = LCASE$( lookFor ) THEN
HasCommandLine = i
EXIT FUNCTION
END IF
NEXT i
ELSE
IF LCASE$( COMMAND$( index ) ) = LCASE$( lookFor ) THEN
HasCommandLine = index
EXIT FUNCTION
END IF
END IF
