API Reference in progress Overview:
For example, character 10 obspy write ascii the "line feed" function which causes a printer to advance its paperand character 8 represents "backspace". Other schemes, such as markup languagesaddress page and document layout and formatting. The ambiguity this caused was sometimes intentional, for example where a character would be used slightly differently on a terminal link than on a data streamand sometimes accidental, for example with the meaning of "delete".
Paper tape was a very popular medium for long-term program storage until the s, less costly and in some ways less fragile than magnetic tape. The Model 33 was also notable for taking the description of Control-G code 7, BEL, meaning audibly alert the operator literally, as the unit contained an actual bell which it rang when it received a BEL character.
Because the keytop for the O key also showed a left-arrow symbol from ASCII, which had this character instead of underscorea noncompliant use of code 15 Control-O, Shift In interpreted as "delete previous character" was also adopted by many early timesharing systems but eventually became neglected.
This technique became adopted by several early computer operating systems as a "handshaking" signal warning a sender to stop transmission because of impending overflow; it persists to this day in many systems as a manual output control technique. Instead there was a key marked "rubout" that sent code DEL.
The purpose of this key was to erase mistakes in a hand-typed paper tape: The Unix terminal driver could only use one code to back up, this could be set to BS or DEL, but not both, resulting in a very long period of annoyance where you had to correct it depending on what terminal you were using modern shells using readline understand both codes.
The "escape" character ESC, code 27for example, was intended originally to allow sending other control characters as literals instead of invoking their meaning. This is the same meaning of "escape" encountered in URL encodings, C language strings, and other systems where certain characters have a reserved meaning.
Over time this meaning has been co-opted and has eventually been changed. An ESC sent from the terminal is most often used as an out-of-band character used to terminate an operation, as in the TECO and vi text editors.
In graphical user interface GUI and windowing systems, ESC generally causes an application to abort its current operation or to exit terminate altogether.
The inherent ambiguity of many control characters, combined with their historical usage, created problems when transferring "plain text" files between systems. The best example of this is the newline problem on various operating systems.
Teletype machines required that a line of text be terminated with both "Carriage Return" which moves the printhead to the beginning of the line and "Line Feed" which advances the paper one line without moving the printhead.
The name "Carriage Return" comes from the fact that on a manual typewriter the carriage holding the paper moved while the position where the typebars struck the ribbon remained stationary. The entire carriage had to be pushed returned to the right in order to position the left margin of the paper for the next line.
By the time so-called "glass TTYs" later called CRTs or terminals came along, the convention was so well established that backward compatibility necessitated continuing the convention. Unfortunately, requiring two characters to mark the end of a line introduces unnecessary complexity and questions as to how to interpret each character when encountered alone.
To simplify matters plain text data streams, including files, on Multics  used line feed LF alone as a line terminator. Unix and Unix-like systems, and Amiga systems, adopted this convention from Multics. The Telnet protocol defined an ASCII " Network Virtual Terminal " NVTso that connections between hosts with different line-ending conventions and character sets could be supported by transmitting a standard text format over the network.
The end-of-text code ETXalso known as Control-Cwas inappropriate for a variety of reasons, while using Z as the control code to end a file is analogous to it ending the alphabet and serves as a very convenient mnemonic aid.
A historically common and still prevalent convention uses the ETX code convention to interrupt and halt a program via an input data stream, usually from a keyboard.Functionality to resample and save full chain history in ASCII files Functionality to lock cells that do not participate in the update of travel time data Work is also ongoing to extend the code to invert for azimuthal anisotropy transtomo.
Introduction This post is associated with a Jupyter notebook available on GitHub.. In a previous post, I explained how to add colour maps to the 3D environment of leslutinsduphoenix.com method is simply to convert the RGB image of the map into an indexed colour image.

I think it is a hard task to write an ebook to an audience so diverse (professional, amateur and noobs) about a topic so wide and complex. It could be useful including a collection of basic url,s classified by topics in order to made easier the learning of shakers.
Since it is a su dataset, I output the offset value into the ascii format and convert it into rsf format. Then this offset header file can be correctly used in sfvscan. If the offset is regularly spaced (e.g. , , ), the sfmath can be used to create such a sequence of header values.
