The numbers 0 through
5 are appended to this prefix to generate the ISPF variable names.
These variables contain the following information:
| prefix0
|
whether the variable is being read or written |
| prefix1
|
the name of the variable that is being updated |
| prefix2
|
the address of the parameter list for the VDEFINE
user exit
|
| prefix3
|
the address of the variable that is being updated |
| prefix4
|
the length of the variable that is being updated |
| prefix5
|
the value of the variable that is being updated. |
For example, if ISPVTVARS=SASVT,
then the variables SASVT0 - SASVT5 would be created. Possible values
for these variables could be as follows:
| SASVT0 |
READ (or WRITE) |
| SASVT1 |
MYVAR |
| SASVT2 |
083C1240 |
| SASVT3 |
00450138 |
| SASVT4 |
7 |
| SASVT5 |
MYVALUE |
