Command Line Interpretor Subroutines

SUBROUTINE SIC_ANALYSE (COMMAND,LINE,NLINE,ERROR)

This subroutine analyses the command line LINE, set up all the internal pointers for argument retrieval, and returns the name of the command found. The line must have been formatted by SIC_FORMAT before being analysed. All active languages are considered, even the ``Library Only'' languages

• COMMAND Character*12, Command name (returned)
• LINE Character*(*), Line to be analysed. It is modified by SIC_ANALYSE
• NLINE Integer. Current length of LINE, modified on return.
• ERROR Logical. Return error code

  SUBROUTINE SIC_FORMAT(LINE,NLINE)

This subroutine does an adequate formatting of any line for later processing by the SIC interpretor. It does not use any internal common of SIC and thus may be accessed independently and considered as a more general routine.

• LINE Character*(*), Line to be formatted.
• NLINE Integer, Current length of LINE. It is modified by SIC_FORMAT and must be initialized so that only trailing spaces appear in LINE after NLINE. A good policy is to initialize NLINE to LENC(LINE).
