REQ

blk2blue.jpg

The REQ attribute (PROP:REQ) specifies an ENTRY, TEXT, COMBO or SPIN control that may not be left blank or zero. The REQ attribute on these controls are not checked until a BUTTON with the REQ attribute is pressed, or the INCOMPLETE() procedure is called.

When a BUTTON with the REQ attribute is pressed, or the INCOMPLETE() procedure is called, all controls with the REQ attribute are checked to ensure they contain data. The first control encountered in this check that does not contain data immediately receives input focus.
