Line 72:

The language used the left-arrow for assignment, {{code|←}}, or the underscore on platforms that did not have [[Stanford ASCII]].{{sfn|Smith|1976|p=5}} It included a number of standard functions like [[square root]], all of the common math operators, and was otherwise similar to most ALGOL derivatives for normal programming.{{sfn|Smith|1976|p=6}}

Strings were manipulated using [[array slicing]], with {{code|aStr[i TO j]}} returning the substring with characters from i to j, or {{code|aStr[i FOR j]}} which returned the substring starting at i and running for j characters.{{sfn|Smith|1976|p=12}} The {{code|INF}}(inity) keyword represented the end of the string, so one could {{code|aStr[i TO INF]}} to return everything from i on.{{sfn|Smith|1976|p=13}} String functions and operators included {{code|EQU}} for testing if two strings were equal,{{sfn|Smith|1976|p=11}}, the ampersand for concatenation, {{code|LENGTH}}, and {{code|LOP}} which removes the first character from the string.{{sfn|Smith|1976|p=12}} There was no way to compare strings other than {{code|EQU}}, operators like {{code|<}} were defined only for numbers.{{sfn|Smith|1976|p=48}}
