FILELIST$ - mkilgore/QB64pe GitHub Wiki

FILELIST$ Function Automatic Setup Version

This version of the FILELIST$ string Function can be set up as a separate Window or be positioned anywhere on program screens larger than 640 X 480. Two position parameters are added to place the top left corner position on a QB64 custom _NEWIMAGE screen. It can be used with ANY screen mode either as a separate window or combined with your program screen! Simply set the parameters to zero if you want to use it as a Window. It will completely restore your program after a file list is displayed. Like the original version, this setup can also be INCLUDEd as a library and supports all of the original file specifications listed on the FILELIST$ (function) page.
