Entering Values

Use

You can assign a value to a screen field either by parameterizing the field in the command interface and then assigning a value to the parameter in the command editor, or by entering a literal directly in the command interface.

In the following table, the first row shows the value that you want to be assigned to a field. The second row shows what you would enter in the command editor to have the desired effect if the field has been assigned the parameter ABC. The third row shows what you would enter if you were assigning the value directly in the command interface.

	SPACE	'	' '	X	'X'
Command Editor	ABC = ' '. CLEAR ABC.	ABC = ''''.	ABC = ''' '''.	ABC = 'X'.	ABC = '''X'''.
