SNOBOL ("StriNg Oriented and symBOlic Language") is a progression of programming languages created somewhere in the range of 1962 and 1967 at AT&T Bell Laboratories by David J. Farber, Ralph E. Griswold and Ivan P. Polonsky, coming full circle in SNOBOL4. It was one of various content string-oriented languages created during the 1950s and 1960s; others included COMIT and TRAC. 

SNOBOL4 stands separated from most programming languages of its time by having designs as a top of the line information type (for example an information type whose qualities can be controlled in all manners allowed to some other information type in the programming language) and by giving administrators to design connection and variation. SNOBOL4 designs are a sort of object and concede different controls, much like later object-oriented languages, for example, JavaScript whose examples are known as ordinary articulations. Likewise SNOBOL4 strings created during execution can be treated as projects and either deciphered or ordered and executed (as in the eval capacity of different languages). 


SNOBOL4 was generally educated in bigger US colleges in the late 1960s and mid 1970s and was broadly utilized during the 1970s and 1980s as a content control language in the humanities. 

During the 1980s and 1990s its utilization blurred as fresher languages, for example, AWK and Perl made string control by methods for normal articulations stylish. SNOBOL4 designs subsume BNF sentence structures, which are proportionate to setting free punctuations and more remarkable than normal articulations. The "standard articulations" in current adaptations of AWK and Perl are in actuality expansions of ordinary articulations in the conventional sense, yet customary articulations, not at all like SNOBOL4 designs, are not recursive, which gives a particular computational bit of leeway to SNOBOL4 designs. (Recursive articulations appeared in Perl 5.10, however, discharged in December 2007.) 


One of the fashioners of SNOBOL, Ralph Griswold, planned replacements to SNOBOL4 called SL5 and Icon, which consolidated the backtracking of SNOBOL4 design coordinating with increasingly standard ALGOL-like organizing, just as including their very own few highlights.
