expr

specifies an expression that equates at run time to the name of an NCL

procedure.

expr

must represent a valid NCL procedure name. The search

sequence followed is:

1. Internal procedure label

2. External procedure name

Note If the label or procedure is not found, NCL generates a run-time error. However, if the FINDRC operand

of the CONTROL verb is specified in the calling procedure, NCL sets the &SYS.RETCODE system

variable to 100. See the first item in “Considerations,” later in this description.

args

specifies a list of arguments that can be passed to the called procedure. You can

pass up to 32000 arguments. If you do not provide a list, no arguments are passed.

When calling an NCL procedure, the variables &1, &2, and so on, to the number

required, contain the arguments provided to the target procedure.

specifies whether the current variable-sharing status is to be overridden for this

function call and whether variable sharing is to be enabled. If this operand is not

specified, NCL uses the setting of the [NO]SHRVARS operand of the CONTROL

verb.

share-list

specifies one or more variables that are to be shared, or not shared, with the

function. The CALLER keyword can be part of the list. The terms must be

separated by commas.

element

specifies a variable type or the CALLER keyword.

specifies any variable type that can be shared, in which the asterisk (*)

can be any combination of characters that can legitimately form a

variable name.

simple-variable

[*]

specifies a simple variable, in which * can be any combination of

characters that can legitimately form a variable name.
