Using loop'd variables

I'm in the process of creating a program for NET SEND use. I'm trying to compare user input to one array. when looping through that array, I want to find a match, keep the index, and use that in another array.

Code: 
sizeOfArray = 4
checked$ = "TRUE"
DIM users$(sizeOfArray)
users$(1) = "Krause"
users$(2) = "Fig"
users$(3) = "Williams"
users$(4) = "Griffith"

DIM usersComp$(1 TO sizeOfArray)
usersComp$(1) = "12"
usersComp$(2) = "18"
usersComp$(3) = "19" 
usersComp$(4) = "20"

validateUser:
FOR i% = 1 TO sizeOfArray
 IF user$ = users$(i%) THEN
  compNum$ = usersComp$(i%)
  checked$ = "TRUE"
 ELSE
  checked$ = "FALSE"
 END IF
NEXT i%

in which I'm trying to keep compNum$ (the variable that is used in the NET SEND), but I'm having problems assigning the i% to it.

Code: 
validateUser:
i% = 1
checked$="FALSE"

do 
  if user$ = users$(i%) then
    compNum$ = usersComp$(i%)
    checked$ = "TRUE"             
  else
    i% = i% + 1
  endif   
loop while (i% <= sizeofArray) and (checked$ = "FALSE")

REM at this point if checked$ is TRUE then i% is the index to userComp$

thanks so much. a few buddies (who asked me to do this) have been continuously pestering me for this since yesterday.

This doesn't work correctly. Its still not saving that number :(

The code works as given. i% contains the index to the matched name in array users$().

Where are you using the variable i%? As given, i% scope is local to the code snippet given. You could always create a function and return the index.

Here is some rather inefficient code:
Code: 
DECLARE FUNCTION ValidateUser% (user$)

DIM SHARED sizeOfArray

sizeOfArray = 4

DIM SHARED users$(sizeOfArray), UsersComp$(1 TO sizeOfArray)

users$(1) = "Krause"
users$(2) = "Fig"
users$(3) = "Williams"
users$(4) = "Griffith"

UsersComp$(1) = "12"
UsersComp$(2) = "18"
UsersComp$(3) = "19"
UsersComp$(4) = "20"

DIM ComputerIndex%, x%

CLS
RANDOMIZE TIMER

FOR x% = 1 TO 20
  y% = INT(RND * 6) + 1

  IF y% <= sizeOfArray THEN
    ComputerIndex% = ValidateUser%(users$(y%))
  ELSE
    ComputerIndex% = ValidateUser%("UNKNOWN")
  END IF

  PRINT "Index = "; ComputerIndex%,

  IF ComputerIndex% <> -1 THEN
    PRINT users$(ComputerIndex%), UsersComp$(ComputerIndex%)
  ELSE
    PRINT "Unknown User", "N/A"
  END IF
NEXT

FUNCTION ValidateUser% (user$)

DIM i%, Checked$


i% = 1
Checked$ = "FALSE"

DO
  IF user$ = users$(i%) THEN
    compNum$ = UsersComp$(i%)
    Checked$ = "TRUE"
  ELSE
    i% = i% + 1
  END IF
LOOP WHILE (i% <= sizeOfArray) AND (Checked$ = "FALSE")

REM at this point if checked$ is TRUE then i% is the index to userComp$

IF Checked$ = "FALSE" THEN i% = -1


ValidateUser% = i%

END FUNCTION

validateCheck:

 GOTO sendMessage
ELSE
 GOTO inquireUser
END IF

whoops.

thats what I'm working with.

compNum$ always comes up blank.

There are quite a few issues with the code as posted, one of which is the code under label validateUser:, which sets compNum$, is never executed after the code under label inquireUser: gets the user name into user$

If you step through the code, you will see other issues as well.

Shows how inattentive I am, I guess. I was looking BEFORE the validation code for the input for user$.
