GET GLOBAL

You can use the GET GLOBAL command to access QMF global variables in your application. For languages other than REXX, QMF provides an extended syntax of the GET GLOBAL command.

|--value lengths--,--values--,--value type----------------------|

The parameters specified on the GET GLOBAL command define the storage that your application program uses to store the variable names and values returned by the GET GLOBAL command.

number of varnames

The number of variables requested.

varname lengths

A list of lengths for each variable name specified.

The length of the variable name should be equal to the actual length of the global variable name in your storage area. An 18-character area padded with trailing blanks is allowed.

varnames

A list of names of the QMF variables.

Because QMF deletes trailing blanks, you should not specify trailing blanks in global variable names.

value lengths

A list of the lengths of the values of the variables.

The following rules apply to the variable value:

• If the value length you supply is less than that of the value stored in QMF, QMF truncates on the right and returns a truncated value.
• If the value length you supply is greater than that of the value stored in QMF, QMF returns a value padded with trailing blanks.
• Integer lengths should always be 4 bytes.

values

A list of variable values.

value type

The data type of the storage area that contains the values. It must be either character or integer.
