ALGO

ALGO is an algebraic programming language developed for the Bendix G-15 computer.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

ALGO was one of several programming languages inspired by the Preliminary Report on the International Algorithmic Language written in Zürich in 1958. This report underwent several modifications before becoming the Revised Report on which most ALGOL implementations are based. As a result, ALGO and other early ALGOL-related languages have a very different syntax from ALGOL 60.

Example

Here is the Trabb Pardo – Knuth algorithm in ALGO:

<syntaxhighlight lang="text" line highlight="1-5,9,10"> TITLE TRABB PARDO-KNUTH ALGORITHM SUBSCript I,J DATA A(11) FORMAt FI(2DT), FLARGE(3D) PROCEDURE F(T=Z) BEGIN Z=SQRT(ABS(T))+5*T^3 END FOR I=0(1)10 A[I]=KEYBD FOR J=0(1)10 BEGIN I=J-10 F(A[I]=Y) PRINT(FI)=I IF Y > 400 GO TO LARGE PRINT(FL)=Y GO TO NEXT LARGE: PRINT(FLARGE)=999 NEXT: CARR(1) END 2END </syntaxhighlight>
