Command$(count%) - I can't get a value when using the optional argument "(count%)" - Unatic - 08-21-2025

Please see the complete program below, and the results of running it with the parameter one two three.
I do not get a value in the optional argument (count1%). it is always zero. Am I reading the WIKI wrong to think that the variable count1% should also contain the value 3 after running the program.

Thanks in advance........

Option _Explicit
Dim cmd$, count1%, count2%
Open "text.txt" For Output As #1
cmd$ = Command$(count1%)
count2% = _CommandCount

Print #1, "Command$="; cmd$
Print #1, "Command$ elements1 cntr ="; count1%
Print #1, "CommandCount$ elements2 ="; count2%
Print #1, "Command$(0)="; Command$(0)
Print #1, "Command$(1)="; Command$(1)
Print #1, "Command$(2)="; Command$(2)
Print #1, "Command$(3)="; Command$(3)
Print #1, "Command$(4)="; Command$(4)
End

Command$=D:\QBTest\CommandUse.exe
Command$ elements1 cntr = 0
CommandCount$ elements2 = 3
Command$(0)=D:\QBTest\CommandUse.exe
Command$(1)=one
Command$(2)=two
Command$(3)=three
Command$(4)=

Option _Explicit
Dim cmd$, count1%, count2%
Open "text.txt" For Output As #1
cmd$ = Command$(count1%) ' <<< this is saying cmd$ = Command$(0) because you never assigned count1% !!!
' just as this line reports!!!
Print #1, "Command$ elements1 cntr ="; count1% ' = 0

count1% is always 0 because you don't make it anything other.

why do you need two variables? to determine how many parameters. are passed from the command line?

Code: (Select All)
Option _Explicit

Dim cmd$, count1%

Open "text.txt" For Output As #1

count1% = _CommandCount

cmd$ = Command$(count1%)

'rest of program

':

that's all there is to it.

if you need the length of the entire command line, use len() on the string.

Thank you for the help and explanation. My tired old eyes were reading the WIKI incorrectly.....
