Puedes utilizar : stringExpression1 contains stringExpression2
y comparas el texto de tu fieldText con el de una variable:
Algo asi, a partir del ajemplo del manual
on mouseDown
digits = "juan"
aLetter=member("texto").text
if digits contains aLetter then
return TRUE
else
return FALSE
end if
end
Syntax stringExpression1 contains stringExpression2
Description Operator; compares two strings and determines whether stringExpression1 contains stringExpression2 (TRUE) or not (FALSE).
The contains comparison operator has a precedence level of 1.
The contains comparison operator is useful for checking whether the user types a specific character or string of characters. You can also use the contains operator to search one or more fields for specific strings of characters.
Example This example determines whether a character passed to it is a digit:
On isNumber aLetter
digits = "1234567890"
if digits contains aLetter then
return TRUE
else
return FALSE
end if
end
