44 procedure Set_Image_Based_Integer
50 -- Sets the signed image of V in based format, using base value B (2..16)
51 -- starting at S (P + 1), updating P to point to the last character stored.
52 -- The image includes a leading minus sign if necessary, but no leading
53 -- spaces unless W is positive, in which case leading spaces are output if
54 -- necessary to ensure that the output string is no less than W characters
55 -- long. The caller promises that the buffer is large enough and no check
56 -- is made for this. Constraint_Error will not necessarily be raised if
57 -- this is violated, since it is perfectly valid to compile this unit with
