How to change the default ICON provided by AcuCobol in your application program
Use the configuration variable ICON. This variable has meaning only on graphical systems such as Windows. Set ICON to the name of the file that contains the icon. This file should be an ".ICO" file that contains a 16-color icon. (Although the file may contain icons in other formats, the runtime accesses only the 16-color icon.) The icon should be created using an icon editor like the one in the Windows Software Development Kit.
For example, if your custom icon were contained in the file "PAYROLL.ICO" in the directory \ACCT\ICONS, you would add the following line to your COBOL configuration file:
The maximum icon size that can be used with the ICON variable is 32 x 32 bits. The runtime uses the first icon it finds in the icon file that fits its maximum. If that icon is larger than the maximum, a memory access violation may occur.
