Info

I BAN K FIN D will start at the current record, and will work its way through the records until it reaches the searched-for string, or the end ofthe second 64K in which the records are stored. It is possible to specify therecord number at which to start from, by including a record number at the end of the command. A further record number, after the starting record number, can be included to specify the record at which to end the search. I BAN K FIN D can be used to look for a string which does not lie at the start of a record. To do this, C H R $ ( e )'s are used in the character positions before the significant characters to be searched for. The CH R $ ( e)'s will be treated as 'wildcards' (like ?'s in CP/M filenames) which means that they count as 'any character'. An example of this would be: a$=STRING$(10,0)+IFRED" IBANKFIND,@r%,a$,0 This would find the first occurrence of the word" F RED" (lying between the eleventh and fourteenth character positions). The first ten characters could contain a phone number or some other information that I BAN K FIN D would ignore. The number of the record in which the string was found is placed in the integer variable r % used for the return code (if the word" F RED" was found), otherwise the return code will contain - 2 . Further details .... Further information about the BANK MANAGER will be found in Chapter 8, and you should study parts 13 and 14 of Chapter 7 on the subject of using RSX's. Finally, check that you have observed the following warnings given at the beginning of this manual, in the section entitled 'IMPORTANT': OPERATION NOTES 1,2,3,9 Foundation Course Chapter 1 Page 91
Well, that concludes this 11 part Foundation course on the CPC6128. By now you should know what most of the keys on the keyboard do, how to use some of the simpler BASIC commands, how to format a brand new disc so that it's ready to use, and how to perform some of the most elementary disc functions, i.e. LOA 0 ing, S A V E ing, CA Taloguing etc, together with a few AMSDOS, CP/M, and BANK MANAGER commands. The chapters that follow, look at the more specialised aspects of computing and AMSTRAD BASIC. There's an in-depth guide to the disc drive section of the unit, with sections on AMSDOS and CP/M, and you will be started off on the road to a new language -Dr. LOGO from Digital Research. Good luck, and happy reading! Chapter 1 Page 92 Foundation Course
