	Buttons can be added to your Business Rules! program to make user input more intuitive. Buttons are made by using the '''B''' attribute on a print fields statement. They set the FKEY value which then can be used to complete an action. Keep in mind that buttons depend on something being done within the program while BR waits for the button to be pushed by the user.

			help text (tool tips) can also be used on a button.

	The next set of parameters specifies the format type of the data to be entered. There are three possible routes.		The next set of parameters specifies the format type of the data to be entered. There are three possible routes.
	In the top route, "~~num~~ form-spec" represents a numeric format specification. G, GL, GU, GZ, L, N, and NZ are all valid in this position; ~~the specification must be followed by a space. The "field-length" parameter~~, ~~which is an integer value that identifies the length (including decimal point and decimal positions) of the field~~, ~~comes next. If the field contains decimal positions~~, ~~"fraction" should identify how many there~~ are; this ~~parameter~~ must be ~~separated from the field length~~ by a ~~period (no spaces)~~.		In the top route, "form-spec" represents either a numeric or string format specification. G, GL, GU, GZ, L, N, and NZ are all valid in this position for numeric fields; C, CC, CR, CL, CU, G, GL, GU, GZ, V, VL and VU are all valid in this position for string fields. The specification must be followed by a space.

	~~In the middle route,~~ "~~string form~~-~~spec~~" ~~represents a string format specification. C~~, ~~CC, CR, CL, CU, G, GL, GU~~, ~~GZ, V, VL and VU are all valid in this position~~.

	The "attributes" parameter represents an insertable syntax that identifies the appearance and control attributes that are to be used for the field.
