This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

GETFLD General field locate routine; can locate a field in the header, format file or curr ent record. GETFRC Find the address of a field in the current record. GETXFL Return first non-space character of a field in the A register, folded to upper case if applicable. SETDPS Set the address of the beginning of the current record. CHKEOF Check the character in the A register for an end of field character. CHKEOR Check the character in the A register for an end of record character. SIZFLD Return the size of a given field. CMPFLD Compare two fields of the same type and set the flags. SCHFLD Return the number of a field, given its name. SCHFLN Return the next field number, given a name, for an ambiguous name specification. GETWID Return the display width for a particular field. GETKYW Return the key width for a particular field. CALSBN Calculate the number of spaces required to be output before a numeric field to right justify it within the display width. GETFLD This routine locates a field in either the database header, the format file or the current record. If the field is in the current record, the address of the first character of the field is set into TEMP06 and also into TEMP07. If the field is in the format file, TEMP07 is left unaltered, and the address of the field is put into TEMP06. If X is equal to 255, then the routine uses the value in the Y register to locate a record in a list of current records. The list of records is numbered from 0 onwards. The usual way to use this part of the routine will be with Y set to zero, in order to locate a field within a single current record. If you are using a list of records, then you must not set Y to too high a value, so that the routine runs off the end of the list, unless you have an end of file marker after the last record. Before you use this routine, you must have set the position of the first record in the list by using the SETDPS call. On entry: A field number of field to locate; field start at 1. X=0 find field in header record. X=1 to find field in format file record; X X=254 gives the number of the format file record. X=255 find field in list of current records; Y has the number of the record to search, starting at zero. Y only significant if X=255. On exit: CS field or record not found; TEMP06 (and TEMP07 if X=255) point to the end of record marker if field not found, the end of file marker if record not found. CC field and record found; TEMP06 points to the beginning of the field; if the call was made with X=255 then TEMP07 also points to the beginning of the field. A,Y undefined. X preserved. GETFRC This call first sets X to 255, and then calls the GETFLD routine. The entry and exit conditions are as for GETFLD when X-255, except that X will always return set to 255. GETXFL GETXFL returns the first non-space character in a field, folded to upper case if alphabetic. It is intended primarily for reading the value of single character fields in the format file, such as the "Field type" field. GETXFL first calls the routine GETFLD. The entry conditions are the same as GETFLD. If the call to GETFLD fails, ie the Carry flag is set, then the A register is cleared, and the routine ends. If the field is found, then the first character of the field is returned, folded to upper case if alphabetic. If the field is blank, then the end of field marker will be returned. On entry: See GETFLD On exit: TEMP06 and TEMP07 set as for GETFLD. CS field or record not found, as GETFLD; A set to zero. CC field found; A contains first non-space character, folded to upper case if alphabetic. X,Y See GETFLD. SETDPS This routine stores the address of the records to be used when using one of the field locate routines with X set to 255. It should be called whenever the address of one of the records in the list or of one of the fields in the records has altered. It need not be called if none of the fields has moved, since ViewStore will keep track of its position in the list of records, and move backwards or forwards as necessary to find the field you have asked for. If you are reading records one by one using the NXTIMF call, for example, then you must call SETDPS with their address of the record for each record that you read: the alignment of the fields will alter for each record. On entry: A contains low byte of the address of the first record in the list. Y contains the high byte of the address of the first record in the list. On exit: A,X,Y undefined.
