[Pascal Language]Managing screens under Pascal
Under Pascal Language screen management is done through functions and procedures of the predefined WinCrt unit. That is why in each program, you have to use the
WinCrt unit (CRT with Free Pascal)
If by default, the title of a window is the name of the source file starting with its path, to modify it, you must put the predefined variable (Table of 80 characters) into the
WinCrt unit:
WindowTitle using the procedure of the Strings unit:
StrCopy.
And to close the window after the execution of the program:
DoneWinCrt.
To move the cursor, use the
GotoXY procedure:
e.g:
Program Management;
Uses WinCrt, Strings;
Begin
StrCopy(WindowTitle, 'STOCK MANAGEMENT');
GotoXY (20, 10); (* row 10 column 20 *)
Write ('*');
Readln;
DoneWinCrt;
End.
