前言自从潮汐资料信息化以来,已有数百站年的资料穿孔纸带用在电子计算机上进行潮汐研究和工程计算。但多数是以手编程序使用的,而对算法语言使用的还不多,其原因是:一方面,潮汐资料是以二一十进制编码穿孔的,并有缺测、缺潮、站、月、日等标志,不能用算法语言中INPUTR过程输入。另一方而,一个站的全年潮汐资料,若按算法语言的数据形式就要占内存11700多个全字长单元,占用数据单元太多,往往会使一些题目因数据单元不够 INTRODUCTION Hundreds of years of information on perforated paper tapes have been used in tide research and engineering calculations on electronic computers since the tide information was made available. However, most of them are hand-programmed, but not much to the algorithmic language. The reasons are as follows: On the one hand, tidal data is perforated with a binary code, and there are missing, Month, day and other signs, can not be used in the algorithm language input INPUTR process. On the other hand, the tidal data of a year of a station, if according to the algorithmic language data form, accounts for more than 11700 full-word memory cells, occupying too many data cells, often causing some problems due to insufficient data cells
