RexxTool

Changelog: version 1.4.4 * RexxMerge.cmd: do not assume that a replacement routine is external; add "procedure" only if either old or new version already has it * RexxMerge.cmd: try to make it run under Regina/OS2 and Regina/linux-- replaced OS2Var() with EnvVar() for Regina changed STDOUT to stdout because Unix/linux has case-sensitive filenames * GetCalls: detect sublabel when execution falls through * Task_Tree: labeled sublabels as external; fixed. * Task_Tree: did not show all routines when -where was not used; fixed. * Task_Tree: display exposed variables for each procedure * Task_CheckExpose: fixed a bug that caused a false warning. Also added a message to point out that an error handler is involved. * added error message if filename has wild characters * added -Decompress switch * fixed bug in Task_VariablesA and MakeVarListsX that did not distinguish between "...then do ; v = 1" and "do v = 1 to 3" * added new option for VARIABLES command. It shows each line where a variable occurs, whether it was assigned or used, and the clause in which it occurs. This is now the default behavior. * added -what=<pattern> switch to CALLS command * GetCalls: fixed self-inflicted bugs from including sublabels-- spurious fall-through call to <sublabel> and missed CALL <sublabel> * MakeVarListsL/E: fixed several (mostly invisible) bugs * Task_UnusedVars: didn't show sublabels; fixed * LabelList(): change default behavior from "with sublabels" to "without sublabels", to be consistent with other routines. * ExpandLabels() now warns about labels not found; removed warnings from routines that call it. * CheckError: check for missing NAME in "signal on Error Errorhandler" * GetCalls: fixed some minor bugs-- exclude sub-labels by default, improved detection in rare cases where execution falls through from [Unlabeled]. * RexxMerge.cmd: added -fte switch to insert folds at imported routines
