  57. "RexxStart()" Bug                                                               
  58.                                                                                 
  59. I use RexxStart() from a "C" program to call a REXX procedure. I have           
  60. recently diagnosed a problem where if I set an environment variable in          
  61. this rexx procedure, the called programs environment is corrupted (as           
  62. a "C" "getenv()" call fails to retrieve a variable that is known to             
  63. exist.                                                                          
  64.                                                                                 
  65. Depending on the change to the environment, I sometimes get an invalid          
  66. value returned in the "pib_pchcmd" field from a "DosGetInfoBlocks()"            
  67. call.  This invalid value is the tail part of the new variable value.           
  68. Thinking that the bug may only occur when expanding the size of an              
  69. environment variable or the environment, I tried to shorten the path            
  70. variable, this removed the problem with "pib_pchcmd" being corrupted            
  71. but still caused the "getenv()" to fail.                                        
  72.                                                                                 
  73. Note that the "getenv()" does not always fail, it obviously depends             
  74. on the change.
