Command-line program utility

The hierarchical code organization is illustrated in Fig. 18.3. This is by code series and then individual codes. ADAS provides extensive Fortran and IDL subroutine libraries which are available for use in a user s own codes and analysis programs. The IDL subroutines support the user s interface to interactive ADAS and graphical presentation of results. Modular basic atomic calculation routines, utilities and access routines to the ADAS data classes are mostly provided in Fortran but generally with IDL versions which use the Fortran through C wrappers. In particular reaEadf .pro and run-adas.pro IDL procedures give access to ADAS data or run ADAS codes at the IDL command line - independent of interactive ADAS. The libraries now include 700 subroutines. 

As of this writing, DOS 6.22 is the most current MS-DOS version available as a stand-alone operating system. Microsoft has included certain DOS-style command line utilities for use within Windows 95, Windows NT and Windows 2000, but these are actually Windows programs that simply mimic the familiar, old command-prompt environment of DOS. 

We will look at a number of graphical utilities in the next few chapters and, believe it or not, the command prompt is one of them. Although you can t tell from looking at it (see Figure 12.20), the crazy thing about the Windows command prompt is that it is actually a 32-bit Windows program that is intentionally designed to have the look and feel of a DOS command line ... 

Open the pulse program ppexamS.seq using the Edit I Pulse program command and replace p2 by p1 2 and place the simultaneous pulses p1 / p4 and p2 / p5 on the same line as shown below. Save the file as ppexamS.seq us ng File Save as. Using the command Utilities I Show pulse program... compare the pulse program scheme with the scheme from Check it 4.1.2.8(a). 

Edit the pulse program ppexam6.seq and change the expression (p1 phi) f1 to include the delay d2 (pi phi d2) f1. Delete d2 on the following line. Save the modified file as ppexamV.seq and using the command Utilities I Show pulse program... compare the new pulse sequence with the "literature" pulse sequence.
