tandem

what is the concept of text, routine , macro and differentiate between them

This is the example we are using those concepts here

?SECTION <program name> MACRO

?SECTION <program name> TEXT

?SECTION <program name> ROUTINE
Solution

  • There are mainly three types of TACL files Macro , Routine & Text.

    Text:- It is simply means that we have bunch of commands we want to execute on Tandem so we create a Text type file.

    E.g. here we want to print bunch of statements so we have created a print TEXT .

    ?SECTION print TEXT
#OUTPUT Hello1
#OUTPUT Hello2
#OUTPUT Hello3

    Routine:- Routine have bunch of arguments which are compulsory to pass when we are executing Routine's on tandem.

    Macros:- Macros have also have arguments but they are not compulsory to pass during execution.
