Calculate the arithmetic average of the numerical expression. Browse the full screen to display and edit the data. Call the binary file CANCEL in the library record running memory to terminate the program execution and return to the point prompt. In multiple-choice statements, specify a conditional change to edit the specified fields and records in the database. Clear the screen, move the cursor to the upper left corner of the screen, clear all, close all open files and release all memory variables. Select workspace CLEAR FIELDS 1 clear field name table CLEAR GETS to build it with the SET FIELDS TO command, and release any variables of the current GET statement from full-screen reading. Clear Memory Clears all current memory variables, programs, program buffers, and pre-inputs. Except for keyboard buffering to close files of the specified type. CONTINUE points the record pointer to the next record that meets the conditions given by the LOCATE command, which appears after the LOCATE command. If there is no positioning, an error will occur. Copy to Copy a database file used by another library file or text file. Copy files Copy any type of file. The copied structure is extended as a record to the structure of the current library file.

FLUSH clears all disk access buffers gatherefrom on records that contain index keywords consistent with the given string. Assign the values of array elements to the current record in the database. GO/GOTO moves the record pointer to the specified record number help to activate the help menu. Explain that FoxBASE+ IF command specIFies the judgment condition in if ... ENDIF structure. INDEX generates an index file according to the specified keyword. INPUT accepts the expression entered by the keyboard and INSERTs a record at the specified location for the specified memory variable insert. JOIN merges the specified records and fields from two database files into another library file. The keyboard fills a string into the keyboard buffer. Labels are printed in the specified label format. Label file list lists records and fields in the database. File list File list File list Current disk directory File list History list Executed command list Memory list Current memory variables and their value list Status list Current system status and system parameters. The list structure lists the library structure of the currently used database. LOAD transfers the assembly language program from disk to memory location and moves the record pointer to the record that is true under given conditions. LOOP skips all statements between LOOP and ENDDO in the loop body. Return to the first line of the loop menu, activate the menu defined by a group of @ ...

If other conditions are specified in the package, all records marked for deletion will be deleted. PARAMETERS specifies that the subprocess accepts the parameters passed by the main process, and the memory variables stored in the subprocess are private, and the attributes of the memory variables are defined as local attributes. A procedure marks the beginning of a subprocess, and PUBLIC defines a memory variable as a global property. Exit Close all files and exit FoxB. ASE+ READ activates GET statement by accepting data input in GET statement, calling, restoring records marked with deletion and deletion, re-indexing, re-establishing original index files in use, releasing and clarifying current memory variables and renaming assembly language subroutines, modifying file names, replacing original contents in database fields with specified data, and displaying datagrams in the form of reports.

Move the pointer back and sort to generate sorted crying file storage assignment statements and based on one or more fields of the database file. Calculates and displays a range of expressions recorded in the database, and suspends the execution of the program. Text ... ENDTEXT displays the current cursor position on the screen ... The text data block is always ahead of time. The sorted files generate a summary file. TYPE displays the contents of the ASCII file. Unlock the locking operation of the current library file on records and files. UPDATE allows batch modification of the database. USE the use command with the file name to open this database file. If there is no file name, close the database file of the current operation and wait for the execution of the suspended program, and press any key to continue ZAP to delete all records of the current database file (unrecoverable).
