Description
Retrieves the value of named variable that was declared using FM.VariableSet.This lookup function returns the default value (or empty) if the variable doesn't exist.
Unlike the variables that were introduced in FileMaker 8 these variables are not limited to the File or Script. In other words they can be retrieved from any file in the system regardless of where they were declared.
You can check with FM.VariableExists whether a variable exists.
Examples
Try it:
"Set: " & MBS("FM.VariableSet"; "test"; "test") & ¶ &
"Lookup test: " & MBS("FM.VariableLookup"; "test"; "not found?") & ¶ &
"Lookup test2: " & MBS("FM.VariableLookup"; "test2"; "not found?")
Example result:
Set: OK
Lookup test: test
Lookup test2: not found?
