- ; This program tests the next of the requesters created by tandem.library,
- ; the TLreqinfo requester. This creates an information box, with an
- ; OK box, and an optional Cancel box, or a designer set of boxes. To
- ; use the TLreqinfo MACRO:
- ;
- ; \1 = stringnum of header, followed by other strings for display
- ; \2 = no. of strings to be displayed (1+)
- ; \3 = 1:ok button 2:ok/canc buttons 3:designer boxes
- ;
- ; TLreqinfo returns choice in D0 (1+), or D0=0 if bad
- ;
- ; If \3=3, then \2 must be 2+. The last string is 1 or more strings for
- ; button contents, separated by \ characters.
