Method 2: Using dynamic allocation

Use this installation method when the SFRXEXEC library is not allocated as part of your logon procedure.

About this task

This installation method requires that you run the IROTXALC REXX EXEC to allocate the EXEC library, SFRXEXEC, to your TSO session. You must run this EXEC each time you logon to TSO and before you want to use this ISPF interface.

Procedure

Modify the IROTXALC and IROTREXL EXEC members. This step only needs to be performed the first time you access this ISPF interface by using this method:
- Modify the IROTXALC EXEC member to include the appropriate high-level qualifier (HLQ) for SFRXEXEC. Follow the comments in the SFRXEXEC library IROTXALC member that describe the available modifications.
- Modify the IROTREXL REXX EXEC member in your SFRXEXEC library to tailor it to your environment. Follow the comments in the IROTREXL member that describe the available modifications.
Execute the IROTXALC REXX EXEC according to one of the following methods. This step only needs to be performed once for each time you logon to TSO. Running this EXEC allocates the necessary ISPF data sets to your TSO user ID.
- If you did not hardcode the high-level qualifier (HLQ) in your IROTXALC REXX EXEC, provide the HLQ parameter as follows:
```
EXEC 'your.hlq.SFRXEXEC(IROTXALC)' 'hlq(your.hlq)'
```
- If you hardcoded the HLQ in your IROTXALC REXX EXEC, eliminate the HLQ parameter as follows:
```
EXEC 'your.hlq.SFRXEXEC(IROTXALC)'
```
