checkPCO

<static> Object checkPCO(text)

5250 PCO.EXE call handler ("RPC from 5250 to client"). This call consistst of the following parts in the 5250 host screen data:
• screen starts at pos=0: hex = a0 or b7.
  this is the host field attribute, mapped as host NUL char
• PCO header: starts at pos=1, len=11, hex = Ø ] P C O 20 c Ø ß Ø Ø
  hex: d8 5d 50 43 4f 20 63 d8 df d8 d8
  first 2 bytes are introducers: hex = d8 5d
  next 4 bytes denote PCO.EXE: ascii=PCO
  next 5 bytes are trailers: hex = 63 d8 df d8 d8, where the last byte indicates "wait for process to finish" (ascii value of \xd8) or "do not wait: (else).
• PCO params: a PC command line.
  start at pos=11, SPACE separated text, terminated by host NUL char hex = a0 or b7.
• Special PCO header: hex = a0 ] P C O 20 c Ø b a0 a0..
The handler checks for this data structure. If found, it parses the PCO call, and calls lwh.pco for handling the command.

Parameters:
the - screen text

Returns:
false indicates "standard screen (no PCO command); else indicates "skip this PCO screen": we have processed the PCO command, and have issued a suitable host response (usually a lwk.send("<ENTER>")
