The strdispose function releases the stack on the stack. The streecopy function copies a string to another string and returns the pointer of the result string string Strend function returns the pointer of the character string STRETCH attribute to automatically adapt the size of the control Strofmt function format The parameter Stricomp function compares two strings (in case case) StringTowideChar function converts the ANSI string to the Unicode string strlcat function to attach characters in a string to another string and return the merged character. Strous strlcomp function Copy the string strlcopy function by maximum length to copy characters in a string to another string StrlFMT function formatted a series of parameters in the string, and the result is included in the result. Pointer strliComp functions pointing to the target buffer compares two strings in maximum length (not case sensitive)

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 into an integer value VaRrayCreate function with a given boundary and dimension to establish a variant of the VARARRAYDIMCOUNT function Returns the dimension of the different body of the VARARRAYHIGHBOUND function Returns to the given variant array dimension Dynasty VararrayLock function locks a given variant array V The ArarraylowBound function returns the lower bound of a given variant array dimension to the specified variant of the array element VararrayRedim function Unlock the specified variant array VARASTYPE function to convert the variant of the VARASTYPE function by changing the upper limit. The Varcase function converts the variant to the specified type and saves his VARCLEAR function to clear the specified variant Varopy function to copy the specified variant to the specified variant varicdatetime function. Returns the variant of the variant VarisArray function test variant is array VariSempty Function Test Variants Whether the Unassigned Varisnnull Function Test Variety is a null VartodateTime function converts a given variant to the date time VARTYPE function converts the variants to the specified type and saves the visibility of his Visible property control. The wantreturns property is When True, press Enter to generate a carriage return; when False, press Ctrl Enter to generate the carriage return Write command to format files, write a variable to file components; write one or write one or Multiple values ​​to the filewriteln command execute the WRITE process,
