POSITRONFIT程序在IBM/PC系列机上的实现

Realization of the POSITRONFIT program on IBM/PC series computers

本文将原POSITRONFIT程序(简称P程序)的参数、数据输入和计算结果输出部分的语句作了大量增删、修改和调整,使之适应于IBM/PC系列机采用的磁盘文件操作系统。用几种PC机FOR-TRAN编译程序对P程序进行了成功的编译(实型量均用8字节的双精度量表示,精度比B6700或IBM370高,计算时间与B6700机相当;用有的编译程序时需修改P程序中的某些开辟数据区的语句以克服编译程序的局限性)。

The parts concerning input and output statements of the original POSITRONFIT program were largely added, modified and readjusted to meet the needs of the PC-DOS operating system. The POSITRONFIT program was compiled successfully by using IBM/PC FORTRAN Compiler V2.00 and IBM Professional FORTRAN Compiler V1.14. The real variables in the program were all expressed by 8 bytes of double precision ones and the precision was better than that on B6700 or IBM370. The typical computational time is 100 seconds, which is a little longer than that on B6700 computer.
