PDP-12 Utility and Data Reduction Programs

This document outlines a collection of software programs for the PDP-12 computer, originally written for the LINC or LINC-8 and modified for the PDP-12. The package includes: - Data Reduction: Programs for autocorrelation (AUTOCOR), frequency analysis (FREQAN, FRQANA), and spectral analysis (FFOURIER/FFSAMPLE). - Utility Programs: Tools for tape manipulation (TAPEDUMP), block searching (SEARCH), comparing tape blocks (COMPAR), and data retrieval (DATAM). - Conversion/System Tools: Programs for converting LAP4 to LAP6 manuscripts, disassembling binary code (BINLAP6), and managing index entries (NU INDEX). - Subroutines: General-purpose subroutines for Q&A (Q&A SUB), parameter transfer (PARAMS), division (DIVSUB), and floating-point arithmetic (SPFLT).

The software operates under the LAP6-DIAL environment. The document provides detailed usage instructions, memory allocation maps, and flow diagrams for each program.
