RexxTool

Changelog: version 1.4.3 * added '-sublabel' switch for GetCalls and ProcMap, so Task_CheckExposed will work on sublabels also. Similar change for MakeVarListsE * RexxMerge.cmd: in a case where the old procedure line is customized with an extra exposed variable, like GetOpts.ReadSwitch: procedure expose flag. str. valid (Shared_vars) and the replacement line is GetOpts.ReadSwitch: procedure expose flag. str. valid the lists of exposed variables will be merged to keep the exposed (Shared_vars) This involved a lot of changes and may have created new bugs. * -check=expose: treat an error-handler as a called routine from every procedure * Tree command: fixed a bug that ignored a top-level routine that calls itself * Change command: reduce the number of unnecessary prompts * Depends command: now shows system commands used * Tree command: added -ascii switch to force using ascii line-drawing characters * fixed: Variables -flat -show=compact showed nothing * fixed: wrong results from Unused -flat * fixed typo in MakeVarListsE that resulted in wrong list of unused variables * ugly, unsatisfactory bugfix in QuotedVar, trying to exclude strings that are not variable names * improved QuotedVar, which was confused by nested functions. Affects Unused and Variables commands.
