Service Prototype
Place the following in a separate copybook for inclusion in both the caller and the service program source members.
**free //============================================================================== // This procedure returns the supplied string as a single-quoted string // with any embedded single-quotes appropriately doubled. //============================================================================== dcl-pr GenUtl_MakeQuotedString varchar(4096) rtnparm; pString varchar(3000) const; end-pr;
Service Procedure
Place the following in a service program source member.
**free
ctl-opt NoMain AlwNull(*UsrCtl) Debug Option(*SrcStmt:*NoDebugIo)
DatFmt(*ISO) TimFmt(*ISO);
//==============================================================================
// This procedure returns the supplied string as a single-quoted string
// with any embedded single-quotes appropriately doubled.
//==============================================================================
dcl-proc GenUtl_MakeQuotedString export;
dcl-pi *n varchar(4096) rtnparm;
pString varchar(3000) const;
end-pi;
return ( ''''
+ GenUtl_ScanAndReplace('''': %trimr(pString): '''''')
+ '''' ); // return resulting entry
end-proc;
