The strlower function converts characters in the string to lowercase strMove functions to copy characters in a string to another string Strnew function allocated a string strPas function on the stack to convert a string StrPas function to a pASCAL class with a string of strings with NULL. String strpcopy functions Copy the string of the Pascal class to the end of the string StrPlcopy function over NULL Copy the maximum length string of the Pascal class to the string StrPos function ended with NULL Back to another string in another string first appearance The pointer strrscan function Returns the final characters in the string StRSCAN function Returns the first character in the string Strtodate function to convert the string to the date format STRTODATETIME function to convert the string to the date / time formatting STRTOFLOAT function to give a given character String transformation into floating point STRTOINT functions convert a string into an integer string to convert a string into an integer or default, the Strtotime function converts the string to the time format STRUPPER function to convert the characters in the string to uppercase style attribute type selection SuCE function returns a subsequent parameter SWAP function exchange parameter High low address bit Tabs Properties tag each item TabINDEX Property tag index text TEXTTOFLOAT function converts strings (with NULL End format) to floating point number Time function returns The current time Timetostr function converts the time format to a string Trim function Delete the front and tail spaces from a given string and the control character trimleft function removes the first space from a given string and control character trimight function from give Deleting the space for the tail in a set string and the control character trunc function intercepts the real value to the integer value Truncate function CAUSELECTECOLOR attributes UNSELECTEDCOLOR attribute Unchetom Upcase Transfer Characters to uppercase Uppercase to give a given character String to the uppercase VAL function converts the string to the integer value of the VARARRAYCREATE function to return the variant of the VARARRAYDIMCOUNT function to a given limit of the VARARRAYDIMCOUNT function returned to a differential change of the VararrayDimcount function returned to a given change. The upper bound of the group dimension of the group dimension, the VARARRAYLOCK function locks the given variant array VaRaylowBound function Returns the lower bound VarrarrayOf function of the array of dimensions. The VararrayRedim function returns the arrayred element of the specified variant to adjust the size of the variant of the VARARRAYUNLOCK function. Unlock the specified variant array VaraSType function converts the variant to the specified type VARCASE function converts the variants to the specified type and saves his VARCLEAR function to clear the specified variant VARCOPY function to copy the specified variant to the specified variant varformdatetime The function returns a variant VarisArray function test variant whether the variant is the array variSempty function test variant whether it is the unassigned varisull function test variant whether the null varicatetime function converts a given variant to the date time VARTYPE function converts variants When the visibility of the specified type and saves his Visible property control is true, press the Enter key to generate a carriage return; for false, press Ctrl Enter to generate the carrier WRITE command to formatted files Write a variable to the file component; write a text file, write one or more values ​​to the filewriteln command to execute the WRITE process,
