I tracked the problem with build-lib.r to syntax errors uncovered by load/header when encountering size literals of the form <num>x<num>. REBOL 2.2.0.3.1 clearly doesn’t understand them: >> val: 1x10 ** Syntax Error: Invalid integer -- 1x10. ** Where: (line 1) val: 1x10 >> val: [ 1x10 ] ** Syntax Error: Invalid integer -- 1x10. ** Where: (line 1) val: [ 1x10 ] I find them in numerous scripts as sizes. Is this a construct that only View understands? Is there any simple fix to build-lib.r? Garold (Gary) L. Johnson DYNAMIC Alternatives [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> 562 802 1639
