Transfer Parameters
Transfer Parameters
Transfer parameters are values which are passed to a function, e.g. the function f$Dialog receives the name of the dialog to be displayed as a transfer parameter.
Almost all system functions use transfer parameters, though decision tables can also be provided with transfer parameters (see DT functions).
Transfer parameters are always enclosed in parentheses. If multiple parameters are present, they are separated by a comma.
Example: | pos = f$FindStr( text, ’:’) |
When calling a function, all transfer parameters must always be specified. A constant, a parameter, or an expression of the appropriate data type can be used in the place of any parameter.
