In a Praat script, you can use numeric expressions as well as string expressions.
You can use a large variety of Formulas in your script:
length = 10
height = length/2
area = length * height
writeInfoLine: “The area is ”, area, “.”
You can use numeric variables and formulas in numeric arguments to commands:
Draw line: 0, 0, length / 2, 2 * height
You can use numeric expressions in assignments (as above), or after if, elsif, while, until, and twice after for.
You can use a large variety of Formulas in your script:
addressee$ = “Silke”
greeting$ = “Hi ” + addressee$ + “!”
writeInfoLine: “The greeting is: ”, greeting$
You can use string variables and formulas in numeric arguments to commands:
Draw line: 0, length (greeting$), 0, 100
Draw line: 0, if answer$ = “yes” then 20 else 30 fi, 0, 100
You can use numeric and string variables and formulas in string arguments to commands:
Text top: “yes”, “Hi ” + addressee$ + “!”
Text top: “yes”, left$ (fileName$, index (fileName$, “.”) - 1)
On how to get information from commands that normally write to the Info window, see Scripting 6.3. Query commands.
