Complex expressions

[Robbyn]

What is wrong with:

let>line1={Upper(%line%)}

MS is reporting a syntax error.

Using the complex expression how do I set out

If>(a=0 or b=0 or C=0) and d>0

Nothing wrong with the expression. You will get the syntax error if "line" has no value.

Using the complex expression how do I set out
If>(a=0 or b=0 or C=0) and d>0

Try this in the editor using the debugger, set different values for a, b, c, d .
Let>a=1
Let>b=1
Let>c=0
Let>d=0

If>{(%a%=0) or (%b%=0) or (%c%=0) and (%d%>0)}
MDL>Conditions were met.
Else
MDL>Conditions were not met
EndIF

Hope this helps,

let>line1={Upper(%line%)}

will give a syntax error if %line% has not been declared yet.

The following works OK:

Code: Select all

Let>line=abcde
let>line1={Upper(%line%)}

======================================

From the Help section on "IF",

Variables must be delimited with % symbols

and from the paragraph dealing with complex expressions you wil find:

//complex expression:
IF>{(%a% = 5) AND (%VarA% = "allen")}
//do something
ELSE
//do something else
ENDIF

Again, as noted above, this will only work after you have declared the variables, so, for your example, you must have:

Code: Select all

Let>a=0
Let>b=0
Let>c=0
Lett>d=5
IF>{((%a% = 0) OR (%b%=0) OR (%c%=0)) AND (%d%>0)}
   //do something
ELSE
   //do something else
ENDIF

Note after posting:
I see that JRL was a bit quicker than me with a solution. Remarkable how similar they both are

Interesting to note the difference between the solutions too

Bob:

IF>{((%a% = 0) OR (%b%=0) OR (%c%=0)) AND (%d%>0)}

JRL:

If>{(%a%=0) or (%b%=0) or (%c%=0) and (%d%>0)}

Bob's is correct.

Although it works in this case, JRL's logic may mean a slightly different thing, in that it "could" mean...

Condition 1: A=0, or B=0
Condition 2: C=0, and D>0

... but that to be safe, the extra ( and ) ensure the conditions are...
Condition 1: A=0, or B=0, or C=0
Condition 2: D>0
