Returns the current value of a CI (MPE XL Command Interpreter) variable.

Syntax

   civar (civarname [stropt])  

This function is implemented by calling the HPCIGETVAR intrinsic.

Formal Declaration

   civar:any (civarname:str [stropt:str="NOEV"]) 

Parameters

civarname

The name of the CI variable.

stropt

A string that determines whether the CI should attempt to evaluate the named variable.

EVALUATE

Evaluate the CI variable

NOEVALUATE

Do not evaluate the CI variable (Default)

This string parameter can be abbreviated.

Examples

   $nmdebug > wl civar ("hpgroup");

   DEMO



   $nmdebug > wl civar ("hpaccount");

   TELESUP

Display the current value of the CI variables named HPGROUP and HPACCOUNT.

   $nmdebug > wl civar( "hpusercapf" )

   SM,AM,AL,GL,DI,OP,CU,UV,LG,PS,NA,NM,CS,ND,SF,BA,IA,PM,MR,DS,PH

Display the current value of the CI variable HPUSERCAPF.

   $nmdat >: :showvar one

   ONE = !TWO

   $nmdat > :showvar two

   TWO = 2



   $nmdat > wl civar("one")

   !TWO

   $nmdat > wl civar("one" "EVAL")

   2

Two CI variables have already been defined. Variable one references variable two which is assigned the value of 2.

The first use of the function CIVAR defaults to NOEVALUATE, and as a result the value of one is returned as !TWO.

In the second use of the function CIVAR, the stropt is explicitly specified as EVALUATE, and so the MPE XL CI evaluates the value of one, which indirectly references the variable two, and the final result of 2 is returned.

Limitations, Restrictions

none
