Sysutils. fmtstr, sysutils. format-format output

Fmtstr is a process that uses the first parameter to return the result. format is a function, and the returned value is the result of the format. For example:

VaR STR: string; begin fmtstr (STR, 'maximum INTEGER: % d', [maxint]); showmessage (STR); {maximum integer: 2147483647} STR: = format ('maximum INTEGER: % d', [maxint]); showmessage (STR); {maximum integer is: 2147483647} {By the way, the showmessagefmt method} showmessagefmt ('maximum INTEGER: % d', [maxint]); {maximum integer is: 2147483647} {their formatting parameters are the same} end;

 

Formatting functions are very powerful, with a special introduction: http://www.cnblogs.com/del/archive/2007/12/18/1005161.html
