Not that I am aware of (maybe utility function in some package though?) but you can easily achieve this using String, or PrintString or ViewString - dependently on the objects that you want to output this way. For example, this is a simple-minded attempt to add some number of spaces in front of an integer (it uses undocumented feature that ListWithIdenticalEntries returns an empty list when its 1st argument is negative): gap> PrintFormatted:=function(d,n) > local t,s; > t:=String(d); > s:=ListWithIdenticalEntries(n-Length(t),' '); > Print(s,t); > end; function( d, n ) ... end gap> for i in [1..16] do PrintFormatted(2^i,4);Print("\n");od; 2 4 8 16 32 64 128 256 512 1024 2048 4096 8192 16384 32768 65536 gap> Hope this helps Alexander _______________________________________________ Forum mailing list Forum@mail.gap-system.org http://mail.gap-system.org/mailman/listinfo/forum
