How can I get mu qbasic script to acceps a external value

[lpb71]

I have written a qbasic script that will edit an ip address within a file depending on what value the script is run with. I can't get my script to accept an external value - ie c:\vlan.exe 10. sample of script below. (In example I want 10 to be passed to my script as the value for vlan$).

LET vlan1$ = "10 10 " + vlan$ + " 1"
LET vlan2$ = "10 10 " + vlan$ + " 8"
'OPEN "c:\SCRIPTS\PROTOCOL.UPD" FOR INPUT AS #2
OPEN "i", 2, "c:\SCRIPTS\PROTOCOL.UPD"
OPEN "o", 3, "c:\SCRIPTS\PROTOCOL.CHG"
WHILE NOT EOF(2)
LINE INPUT #2, a$
IF a$ <> "DefaultGateway0=changeme" THEN PRINT #3, a$
IF a$ = "DefaultGateway0=changeme" THEN PRINT #3, "DefaultGateway0="; vlan1$
WEND

Done this by getting my script to read an unput file.

If you're using QBasic 4.5 you can easily use the COMMAND$ function, witch return the used command line parameters.


LET VLAN$ = COMMAND$
(remaining code)

Note to all:

Noone uses Let anymore. It's only included to be backward
compatible.

Let A=1
is exactly the same as
A=1
and 4 less bytes when saved in ascii file format

LOL...

I was about to say...

Do you REALLY still use LET ???

That was only carried over for compatability reasons from gwbasic...
(That's like using line numbers... Please say you don't do that ;-))

It's easier for a beginner to understant what "LET" let you do, and it can be useful when you want to search your code for variable change and not for comparison, but you're right it takes too much place for something not necessary at all. I used to take "LET" on the TRS80, and it's a good things it is not necessary anymore!
