Description
The ALIAS command allows for the definition of User Defined Commands (UDCs). The ALIAS command, on its own, causes all active UDCs to be listed.
<expC>
The <expC> is the name to call the user-defined command. The ALIAS <expC> without a subsequent <command> statement removes that UDC.
<command>
The <command> character expression can contain multiple Recital/4GL commands, each separated with a ';'. Up to nine parameters may be substituted by preceding the parameter number with a '%' character, e.g. %1 %2 etc. Parameter %0 matches the complete line following the command name.
Example
alias lm "list memory" && defines lm alias lo "list off" alias l "list off for ord_id = [%1]"
Products
Recital Database Server, Recital Mirage Server, Recital Terminal Developer
