HPCICOMMAND intrinsic
• HPCICOMMAND is an intrinsic
syntax: HPCICOMMAND (cmdimage,error,parm
[,msglevel])
• implemented in native mode (NM, PA-RISC mode)
• use HPCICOMMAND for a “window” to the CI, e.g.:
• providing a command interface to a program, “:cmdname”
• UDCs searched first
• command file and implied program files searched
• returns command error number and error location or file system error number.
• Msglevel controls CI errors/warnings -- similar to the HPMSGFENCE variable
