CALL NEXTWORD();

Details

A word is the text at the current position up to the next blank or semicolon. A semicolon denotes the end of a command in addition to the end of a word. NEXTWORD is used with WORD and is usually used in conjunction with CONTROL ENTER, CONTROL ALWAYS, or CONTROL ALLCMDS.

If the command line contains two or more commands separated by semicolons, then only the first command on the command line is executed during the current execution of the MAIN section. The next command is executed when control is returned to the program or when another entry is displayed, as in the use of the DISPLAY routine.

Example

If a user issues the command AXX BXX CXX DXX, the succession of words is as follows:

	Initial	After 1st NEXTWORD	After 2nd NEXTWORD
word(1)	AXX	BXX	CXX
word(2)	BXX	CXX	DXX
word(3)	CXX	DXX	blank
