Three possible bugs I have noticed in 2.02 beta port of Gawk to IBMPC recently posted to binaries: 1) The '+' regular expression operator does not seem to work. Ex: Given a data input file containing lines 1aa1 2bb2 1aa2 1aa1 The pattern/action command: /1a+1/ {print} does not work (nothing prints), whereas equivalent /1aa*1/ {print} works as expected (two lines printed). 2) AWKPATH setting is ineffective in allowing lookup of source files. The documentation is somewhat sparse on the exact format - I have tried every standard MSDOS or UNIX type format I know - none worked. If anyone has in achieved results with the AWKPATH environment var please inform me as to exact syntax used in setting it. 3) system(cmd-line) function does not work. Documentation notes disclaimer for non-Unix or GNU systems, but should not be gravely difficult to implement this useful feature given C lib system() call. If you have had success with these features please notify me as to my error. Else help transmit this bug report to original porter of Gawk to PC (I have neither name nor address). The executable posting did not include source. If anyone has source to this PC version (Gawk 2.02beta) please mail it to me.
