- 1- Usage 2- Examples of Use
-
-
-
- CLRCST can be used to improve the utility of custom shells created as
- aliases and installed with SHSET. Standard ZCPR3 does not allow memory-
- resident flow control commands to be processed properly in this situation.
- Rather than modifying your ZCPR3 code, you can use CLRCST to remedy this
- defect.
- :1
-
-
- Usage: Run CLRCST (Clear-Console-Status) before any flow control
- commands are executed in the shell-alias.
- :2
-
-
- Examples of Use:
-
- a. Create the following alias called TEST:
-
- ECHO DO IT AGAIN?;IF IN;ECHO OK, AGAIN;ELSE;ECHO DONE;FI
-
- and run it with the command: SHSET TEST
-
- If your system is standard ZCPR3, it should halt with an error message
- (or possibly loop forever) upon encountering the ELSE clause (or
- possibly the IF clause if IF.COM is not available). If it does, insert
- the command CLRCST at the beginning of the alias and try it again.

-
- Examples of Use (continued):
-
- b. One application of this feature is with FOR/NEXT processing,
- as shown by the following example alias:
-
- CLRCST
- NEXT VAR
- RESOLVE IF -%VAR=-
- SHCTRL P
- ELSE
- <additional commands, possibly using the variable>
- FI
-
- This technique can be applied wherever definite or indefinite
- command loops are required.
