The VDEFINE service is invoked by a program to give ISPF the ability to use dialog variable names to directly access variables within the particular program module. In the call to VDEFINE, the program specifies the format (character string, fixed binary, bit string, hex, float, pack(n), b...
ansible.builtin.template:src:foo.cfg.j2dest:'{{remote_install_path}}/foo.cfg' In this example, the variable defines the location of a file, which can vary from one system to another. Note Ansible allows Jinja2 loops and conditionals intemplatesbut not in playbooks. You cannot create a lo...
A program written in TELCOMP, an interactive-computer language, is presented for doing all the necessary computations for the Johnson-Neyman (1936) technique in the simplest case, starting from raw sums, sums of squares, and sums of cross-products or from means, standard deviations, and ...
Something else to keep in mind when naming variables, is that they are case-sensitive, meaning thatmy_int,MY_INT,My_Int, andmY_iNtare all completely different variables. You should avoid using similar variable names within a program to ensure that both you and your current and future collabo...
If filename is a MAT-file, then load(filename) loads variables from the file; if filename is an ASCII file, then load(filename) loads a double-precision array containing data from the file. Note Security Considerations: The load command might execute code contained in a MAT-file as it ...
The program declares two variables with the shorhand notation in one line. Go variable default valueVariables declared without an explicit initial value are given their zero value: 0 - numeric types false - boolean type "" - string typedefault.go ...
A similar technique can be used in application programs to construct SQL statements using program variables, as shown here using PHP 5: <?php$mysqli=newmysqli("localhost","user","pass","test");if(mysqli_connect_errno())die("Connection failed: %s\n",mysqli_connect_error());$col="c1...
