If then and loops

[Nick G]

I'm having trouble with the below code. E-Prime seems to want a
'then' statement immediately following the 'if' statement:

if present.RESP = "z" and strHit2 = "aHi" or strHit2 = "aLo" strHit2 =
"aMed" then
Confidence.RESP = strHit2

If one response on the present slide is selected, I just want E-Prime
to allow one of the three responses in the string hits. How should
this code look?

[Peter Quain]

try searching e-basic help for "If...Then...Else (statement)". Note
the conditions under which you need to close the conditional with "End If"

The E-basic help doesn't say whether an if-then statement can have
multiple conditions. Seems limiting to not have that sort of
functionality.

You know in C you can just
if (condition1 && condition2)

[Peter Quain]

Note in description: "statement or group of statements."

-----------------------
Syntax 1

If condition Then statements [Else else_statements]

Syntax 2

If condition Then
[statements]
[ElseIf else_condition Then
[elseif_statements]]
[Else
[else_statements]]
End If
-------------------------
Description

Conditionally executes a statement or group of statements.

Comments

The single-line conditional statement (syntax 1) has the following parameters:

Parameter Description

condition Any expression evaluating to a Boolean value.
statements One or more statements separated with colons. This
group of statements is executed when condition is True.
else_statements One or more statements separated with colons. This
group of statements is executed when condition is False.

The multiline conditional statement (syntax 2) has the following parameters:

Parameter Description

condition Any expression evaluating to a Boolean value.
statements One or more statements to be executed when condition is True.
else_condition Any expression evaluating to a Boolean value. The
else_condition is evaluated if condition is False.
elseif_statements One or more statements to be executed when
condition is False and else_condition is True.
else_statments One or more statements to be executed when both
condition and else_condition are False.

Google can be your friend:

Using If...Then...Else Statement

      ' Dimension the variable.
      Dim x As Integer
      ' Place a value in x.
      x = Int(Rnd * 100)
      ' Display the value of x.
      MsgBox "The value of x is "
& x & "."
      ' Test to see if x less than or equal to
10.
      If x <= 10 Then
         ' Display a message
box.
         MsgBox "X is
<=10"
      ' Test to see if x less than or equal to
40 and greater than 10.
      ElseIf x <= 40 And x > 10 Then
         MsgBox "X is
<=40 and > 10"
      ' Test to see if x less than or equal to
70 and greater than 40.
      ElseIf x <= 70 And x > 40 Then
         MsgBox "X is
<=70 and > 40"
      ' Test to see if x less than or equal to
100 and greater than 70.
      ElseIf x <= 100 And x > 70 Then
         MsgBox "X is <=
100 and > 70"
      ' If none of the above tests returned
true.
      Else
         MsgBox "X does not
fall within the range"
      End If

In E-basic help look for "And (operator)" ... links to other
operators at bottom of the page.

[Michiel Spape]

Avoiding pedantry:
In basic you can just
if (condition1 and condition2) then ... which works almost exactly the same as the & in C (but not &&, which would be if (condition1) {if (condition2) {...}}.

Anyway, the answer is much shorter:
IF (present.RESP = "z" and strHit2 = "aHi") or (strHit2 = "aLo" and strHit2 = "aMed") THEN

Confidence.RESP = strHit2

END IF

Note the end if. All on one line is also possible, but note it freaks out if you then use end if. THIS is what is exasperating - if not necessarily limitating - about ebasic.
More likely, your code makes no sense in some other degree, though. Notice me putting in the brackets - they are useless - and comes before or anyway - but i think where you got stuck was in the length of the IF statement. I mean, strHit2 is never both aLo and aMed, right? In your original code it did not have an operator (or strHit2 = "aLo" strHit2 = ?), so, given a wild guess, you actually want something like this:
IF present.RESP = "z" and (strHit2 = "this" or strHit2 = "that" or strHit2 = "nothisactually") THEN
Confidence.RESP = strHit2
END IF

Notice that due to the precedence of and over or - both in C and basic - this is possible, but your previous code made little sense.
Best,
Mich
