Abstract : This document describes LCC, a Language for Conversational Computing which runs under TSS on an IBM 360/67. The statement syntax of LCC stems from that of Algol 60 and JOSS, but LCC has been designed to exploit as fully as possible the dynamic nature of conversational computing. Thus LCC is a fully interpretive system with extensive features for conversational control and with capabilities for dynamic block structure, block expressions, and recursion, interspersed editing and execution (use of program text as data and vice versa), dynamic variable attributes, and interlaced program execution and creation (program-directed program preparation). The complete LCC syntax and a sample conversation are included.
